git-diff-goto-source is specific to diffs produced by Git. This patch
generalizes the logic and moves it to a new diff-jump in diff.kak.
The main differences are:
- diff-jump handles plain file diffs (i.e. without the -r option). These
have no "diff" line. This means that it needs to parse +++/--- instead.
- diff-jump can go to the old file, not just the new one.
- diff-jump allows to override the base directory and the number of
directory components to strip.
git-diff-goto-source was implemented with several nested try/catch
blocks. Implementing the extra features would have added more
nesting, redundancy or hidden options. To avoid that, I ported the
parsing logic to Perl (which git.kak already depends on). Maybe
it's possible to do the same in awk.
Potential concerns:
- We could move diff-jump to a new rc/tools/diff.kak but then it's not
obvious where the "diff" module belongs to.
- Should diff "diff-jump -1" be spelled "diff-jump -p1"?
In future, the diff parser could be reused to implement a vimdiff-style
feature: given a diff and the "old" line number, we can compute the
corresponding "new" line number. Perhaps diff-jump should get a -client
argument.
We want to move git-diff-goto-source from rc/tools/git.kak
to rc/filetype/diff.kak (or should we could create
rc/tools/diff.kak?). Either way, create the diff module so we can
formalize this dependency.
Currently this module only provides highlighters, so require it
wherever we reference them.
Keep the diff-select-{file,hunk} commands outside the module because
people might already use them in git buffers.
This will unfortunately break some use case which will require
using wrapper scripts to add the necessary newline. It is however
harder to do the contrary, and it makes a lot of other use case
possible, such as checksuming.

After a while it seems clear changing this is much more ergonomic
and restoring it with pure config is impractical as we need to map
all lower case keys.
Cross-reference the "completers" option, and explain how filtering works.

As reported in [1], completions provided by "set global completers
option=my_completion" activate insert mode autocompletion, even when
the autocomplete option does not have the insert mode flag.
This happens because InsertCompleter::on_option_changed() calls
InsertCompleter::setup_ifn(), which shows the completion pager.
Fix this by computing whether the completion pager is enabled;
otherwise we can return early from setup_ifn().
The completion pager is enabled if the autocompletion bit is set,
or if the user has requested explicit completion.

When `set` or `se` is found at the start of the modeline, it should stop parsing options after `:`.
When `modeline-parse` is called in the following file, it should _not_ recognize `tabstop=4` and `invalid_option=3`.
```
# kak: set indentwidth=0 tabstop=16: tabstop=4 invalid_option=3
```

Now that it is, we get the following error when trying to execute
`test/compose/select-display-columns`
```sh
./enabled: 2: [: 4: unexpected operator
```
This commit fixes the enabled check
Even though the synopsis mentioned `kak -f` accepts filenames, it wasn't clear
to me that Kakoune would filter them in-place by default (I guess I assumed it
would write them to stdout like sed(1)).
In normal mode, the mode line contains "1 sel" or "n sels (k)" when n > 1,
whereas in insert mode, it contains "n sels (k)" even for n == 1. Change
the contents in insert mode to match normal mode.

trim_indent call was incorrect, trim_indent is intended to work

benefit from a better name).
Fixes#4378
adds the ability to press <ret> within a hunk and navigate to the original
source code. This can be useful because one often needs to go back and forth
between the diff and the full source code.
- You can press <ret> anywhere _within_ a hunk i.e. lines that start with
` `, `+`, `-`. You will be taken to the exact line in the source that corresponds
to where you pressed <ret> in the hunk. It actually does not make sense
to press <ret> on a `-` line because that does not exist anymore but
in that case you are taken to a nearby line in the hope this is still useful.
- You can also press <ret> on a range line (lines that
look like @@ ... @@). If you press <ret> on anywhere on a range line e.g.
```
@@ -120,3 +123,4 @@ fn some_function {
```
The code will try to navigate to the section heading "fn some_function {"
Note that the section heading is _not_ necessarily located at the
range line (in the above example the range line is 123).
- You can press <ret> on a +++ line also and you will be taken the first
line of the file
Caveats:
- Navigation to the original source file will be accurate only if any edits to
the original source file have been saved to disk, because otherwise
they will not be detected by the `:git diff` or `:git show` commands
- This feature should work well for most typical uses e.g. `:git diff`, `:git diff HEAD^`
`:git diff <some-sha1>`. In fact this feature should work in all scenarios when
the *current files* on disk are being compared _with_ some arbitrary git revision/staging.
It will be less useful in other scenarios when two arbitrary revisions are being
compared to each other or when you are trying to compare staging to some revision.
For example when you invoke `:git diff --staged` you are trying to compare staging
with HEAD but are navigating to what is currently on disk (which may be different
from staging).
