Mapping upper case keys is legitimate, for exampled so that they behave
the same as a lower case mapping. The current rejection of those mappings
is a misguided attempt to prevent mapping *to* upper case keys as those
will never get triggered.

Originally the page said:
> No other escaping takes place in balanced strings.
...but in the course of a general readability rewrite (56287da) this was
changed to:
> Characters may be escaped in the same manner as those for quoted strings.
...which is not actually true; probably this change made it in because there
were a lot of good changes in those commits and we didn't read them all closely
enough.
Now the documentation is correct again, and I've added some examples covering
the problems people occasionally ask about (see #2760).
When running modeline-parse on this file:
# kakoune: filetype=ledger:indentwidth=4
I get this error from dash (and a similar one from bash):
sh: 53: readonly: key: is read only
This is because the readonly variable "key" is used elsewhere, both
times as global. Fix this by making both variables local. While
at it, remove an unused variable.
Fixes#4478
This is equivalent to a change to grep.kak in 649e252f7 (bring *grep*
buffer to front in context of toolsclient, 2020-08-14).
If a toolsclient is set, make-next-error (and make-previous-error) will
jump to %opt{make_current_error_line}. This is wrong if the toolsclient
does not show the *make* buffer. In that case make_current_error_line
is undefined and we end up showing the goto menu. This has occasionally
been annoying me for a long time but I never bothered investigating.
Fix this by switching to the *make* buffer. The potential downside
is if make-next-error is run from the toolsclient, where we no longer
jump to the error but that's fine because we can use <ret>.
We can maybe improve this later by extending the logic, see
https://github.com/mawww/kakoune/pull/3656#pullrequestreview-472052285
After a failed
:write file-that-already-exists
a user might want to type ":<up> -f<ret>" to force-overwrite.
This doesn't work because :write's switches must precede the filename.
It's dual :edit does not have this restriction.
Some commands require switches to precede positional arguments for a
good reason; for example because positional arguments might start with
"-" (like ":echo 1 - 1").
There seems to be no reason for the :write restriction, so remove
it. Same for :enter-user-mode.
Thanks to alexherbo2 for reporting.
I can't think of a case where a URL would not start at a word boundary.
Let's add that to the regex. In addition to correctness, this also
slightly improves performance because matching can stop earlier.

Running %sYeti<ret>casdf on file
[example.journal.txt](https://github.com/mawww/kakoune/issues/4685#issuecomment-1193243588)
can cause noticeable lag. This is because we insert text at 6000
selections, which means we need to update highlighters in those lines.
The runtime for updating range highlighters is quadratic in the
number of selections: for each selection, we call on_new_range(),
which calls add_matches(), which calls std::rotate(), which needs
needs linear time.
Fix the quadratic runtime by calling std::inplace_merge() once instead
of repeatedly calling std::rotate(). This is works because ranges
are already sorted.
I used this script to benchmark the improvements.
(In hindsight I could have just used "-ui json" instead of tmux).
