b1f5639d8c src: Add support for right click events 
The current implementation treats left mouse button clicks as a
generic "mouse press" modifier, this commit extends the list of
modifiers by adding a "right mouse click" one.

The proper way to implement this would be to ship the coordinates
of mouse key press events in each `Key` object, and pass whichever
button was clicked as a codepoint value (instead of coordinates
currently), but this would require more work.

This commit allows:

* right clicks to set the cursor of the main selection
* control-right clicks to merge all the selections, and then set
  its cursor

af5d2d9523 Parse xterm-keys for motion directly 
Ideally, something better should be done (re #2554) but this is a decent
intermediate step for some useful keys.

Note: NCurses supports parsing these keys when shifted (KEY_SR,
_SLEFT, S_RIGHT, etc), but it does not do the same thing for the other
modifiers.

a4f830f143 Use _exit() after vfork() 
Closes #2620

POSIX.1-2008.

7fea08e736 src: The test build target depends on kak 
Not having the `test` target (in the Makefile) depend on the `kak` one
prevents users from running commands that make use of parallelism, e.g.:

$ make -j all test

The above command sometimes results in the test suite running before
the binary has been compiled and symlinked, resulting in failures.

b897a18aa6 Use a dummy function for SIGPIPE instead of SIG_IGN 
SIG_IGN is inherited after 'execve' and requires us to reset
that signal handler, which does not work well with vfork on
OSX. Using an empty function does the trick and will be auto
reset to default on exec.

5250593129 ShellManager: Use vfork instead of fork 
When large buffers have been opened, copying Kakoune's memory
page descriptors can get pretty slow, making fork more expensive
than necessary.

vfork avoids that problem. While not strictly conforming, it seems
the few calls we do before execve (open, close, dup2 and
set_signal_handler) would not cause any problems on platforms we
care about.

194a5db5d6 maintain a list of valid ranges for region highlighting 
This should greatly reduce memory usage by only caching matches
for ranges that needs to be highlighted, in the case where multiple
regions are nested, this means only the topmost region needs to parse
and cache the whole buffer, other regions highlighter will only ensure
the lines for the ranges they are called up are cached.

if the regions start/end/recurse match is less than 65635 byte long.
With this limitation we can reduce the RegexMatch struct size to 16
bytes instead of 32.

This is still not good enough,but should slightly improve high memory
usage as reported in #2454

ab6bc41358 Added shell command completion support to define-command and prompt 
This commit also introduces a regression in that I decided that the best way to
avoid overly long and confusing names was to rename the current shell-*
switches to script-*, and have the shell command completion be
shell-completion.

renamed script-{completion,candidates} to shell-script-*

Updated docs with new switch names

Added -shell-completion switch to x11-repl and kitty-repl

Final is more granular, it consists of FinalFg (f), FinalBg (g)

fully overwrite the previous face (instead of merging) and if
following faces apply on top of this face or not.

by it (I might accept a few additional ones, such as <c-w>, but not
too much, I still see that as a hack pending a nicer solution).

82c01c5dd3 Speed up wrapping at word boundaries. 
Previously, when wrapping lines at word boundaries, we would iterate forwards

which was horribly slow.

Now we record the last word-boundary we saw as we iterate forwards, getting a
result in one pass.

b548dd3a6f Change option lists to be specified as separate arguments on commands line 
Option lists and maps are specified using separate arguments, avoiding
the need for additional escaping of their separator and reusing the
existing command line spliting logic instead.

As discussed on #2087, this should make it much easier to work with
list options, and make the general option system feel cleaner.

c829595d01 Refactor command line parsing 
Command line parsing now works as follow:

* Quoted strings ('...', "..." and %~...~ with '~' non nestable)
  use 'doubling-up' for escaping their delimiter, if the delimiter
  appears twice in a row, it is considered as part of the string and
  represent one delimiter character. So 'abc''def' == "abc'def". No
  other escaping takes place in those strings.

* Balanced strings (%{...}) do not support any kind of escaping, but
  finds the matching closing delimiter by taking nesting into account.
  So %{abc{def}} == "abc{def}".

* Non quoted words support escaping of `;` and whitespaces with `\`,
  `%`, `'` and '"` can be escaped with `\` at the start of the word,
  they do not need escaping (and will not be escaped) else where in
  a word where they are treated literally. Any other use of '\' is a
  literal '\'. So \%abc%\;\ def == "%abc%; def"

As discussed in #2046 this should make our command line syntax more
robust, provide a simple programmatic way to escape a string content
(s/<delim>/<delim><delim>/g), be well defined instead of ad-hoc
undocumented behaviour, and interact nicely with other common
escaping by avoiding escaping hell (:grep <regex> can in most case
be written with the regex unquoted).

ec16969609 Do not reparse %sh{...} strings 
Automatic reparsing of %sh{...}, while convenient in many cases,
can be surprising as well, and can lead to security problems:

'echo %sh{ printf "foo\necho bar" }' runs 'echo foo', then 'echo bar'.
we make this danger explicit, and we fix the 'nop %sh{...}' pattern.

To reparse %sh{...} strings, they can be passed to evaluate-commands,
which has been fixed to work in every cases where %sh{...} reparsing
was used..

This commits changes the way `C` behaves when the next line is empty:

The primitive's count parameter holds the maximum amount of selections
that should be added to the current one.

539832bf29 Add position offset to Window to limit moves with search menu style 
Window can be resized with an "offset_pos" flag, which means that
the resize took place on the top left corner of the window, leading
to a change in current window position. This is treated as temporary
and the position change is stored in a m_position_offset field.

That allows the ncurses UI to offset the position when it displays
a Search menu, so that the window does not constantly scroll when
the search menu open/closes. The window will only scroll if it needs
to in order to keep the main selectin visible.

5fa19f4d7f NCursesUI: Add support for shifted function keys 
Shifted function keys are not well standardized around terminals,
Shift F(N) usually returns F(X) + N, with X=12 on xterm, X=10 on
rxvt-unicode... Default to X=12 and make it configuable through
the ncurses_shift_function_key ui_option.

This fixes what #1898 tried to.

50e422659b Add support for the shift modifier. 
Because keyboard layouts vary, the shift-modifier `<s-…>` is only supported
for special keys (like `<up>` and `<home>`) and for ASCII lowercase where
we assume the shift-modifier just produces the matching uppercase character.
Even that's not universally true, since in Turkish `i` and `I` are not an
uppercase/lowercase pair, but Kakoune's default keyboard mappings already
assume en-US mappings for mnemonic purposes.

Mappings of the form `<s-x>` are normalized to `<X>` when `x` is an ASCII
character. `<backtab>` is removed, since we can now say `<s-tab>`.

08df409a53 RankedMatch: Do not compare word boundary match count on single word matches 
As the computation of word boundary matches is separate from the
actual subsequence matching, we sometimes have candidate that match
as a single word while still having multiple word boundary matches.

For example, with query "expresins", candidate "expressionism's"
will match as single word ("expressins" is a subsequence of
"expressionism"), and will have two word boundaries match (it does
match the last "s", which is considered as a separate word).

This should not be taken into account when compared against
candidate "expresions", which should be considered a better
match.

6a6e71dc0f Highlight cursors differently when they lie on an end of line 
When on an end of line, certain behaviours can be surprising, for
example delete will join the following line (which makes sense, and
is consistent, but hard to predict if we do not know the cursor is
on and end of line).

As Kakoune is moving more and more towards treating end of lines

a0de41d165 goto last change: do not try to avoid end of lines 
Avoiding end of line is a behaviour we avoid (pun intended) more and more
in Kakoune source code, now that end of lines are regularly selected, it
makes no sense to just to next line when last modification lies on an EOL
(and it probably did not make much sense back when that code was written).

This should not be necessary as :exec/eval already save those registers

4d11bb20c3 Always collapse jumps in exec/eval, remove -collapse-jumps switch 
There does not seem to be any reasonable use cases of not collapsing
jumps when the input is not comming from the user. Always collapse
them.

It could make sense to move jump collapsing out of context_wrap as
in general any action not comming directly from the user should
collapse them, at the moment a comment or mapping will not collapse
jumps, which is unfortunate.

66fe2d84da Refuse modification of ReadOnly buffers and make Debug buffer readonly 
The debug buffer is a bit special as lots of events might mutate it,
permitting it to be modified leads to some buggy behaviour:

For example, `pipe` uses a ForwardChangeTracker to track buffer
changes, but when applied on a debug buffer with the profile flag
on, each shell execution will trigger an additional modification
of the buffer while applying the changes, leading to an assertion
failing as changes might not be happening in a forward way anymore.

Trying to modify a debug buffer will now raise an error immediatly.

81eb2ee428 Do not strip whitespaces with '*' 
Stripping whitespaces there is a failed experiment as it breaks the
ability to use multi-selections consistently: Using '*' followed by some
`N` to add following matches, we end up with mismatched selections
due to whitespace stripping the original selection still contains
whitespaces where all the new ones do not. Once we get to this state,
most selection commands will give different results for the initial
selection and the other ones, breaking predictible multiselection use,
one of the cornerstones of Kakoune editing model.

29a7cd3ab4 Insert complete: Remove path info with one buffer 
This change is useful when using `set scope completers word=buffer`,
instead of the default word=all.

If candidates all come from the same buffer, then the path/filename
information is the same and therefore unnecessary. This change
prevents the same path from being repeated, and the buffer's
source code is less obscured.

More generally, there could be an option to disable the path
information entirely in all cases, but for now this change seems
a reasonable solution until any such option exists.

This approach was suggested by PR #1786 but the implementation here

to strings.

This is also the prefered way to work only on the main selection:
save selections with Z, reduce to main with <space>, restore with z.
