In a noninteractive shell, asynchronous commands ignore SIGINT and
SIGQUIT. We typically use such shells to feed fifo buffers which we
do want to cancel them on Control-C. Make it so.
Same for SIGQUIT; that one is not typically used but I expect that
along the Kakoune server it kills any child processes that (haven't
been daemonized).
Note that for unknown reasons, Bash already doesn't ignore SIGINT in
async processes that use "eval".
Note that Dash has a bug that prevents this from working;

(While at it balance out some parens, to help the m command)
`grep-next-match` works only on the `*grep*` buffer so it can't be used
on buffers that were preserved by renaming or on other grep-flavored
buffers created by 3rd party plugins kakoune-find and kakoune-lsp,
like `*find*` and `*references*`.
Let's generalize `grep-next-match` with a `jump-next` command that
takes a buffer argument.
This renames some options but I think they're not commonly used.
kakoune-lsp is an exception that uses grep_current_line but it's no big
deal, things will fail loud and early if options are missing.
Since grep.kak and friends now depend on jump.kak, move the jumpclient
declaration there as well.
Since the default make error pattern spans until the end of the
line, make-jump select the whole line, moving the cursor to the end.
This is especially bad when the error message is very long and hence
the cursor movement scrolls the viewport so the file:line:col is no
longer visible.
Stop moving the cursor in `*make*` and `*grep*` buffers.
We already have highlighting to indicate the current line.
If a user modifies a grep buffer, we can end up in weird situations
where we try match a filename over multiple lines.
Let's rule out newlines in filenames here. There is an argument
this is a case of GIGO but we already do this for the corresponding
highlighters.
We also do it in make.kak, see ca225ad4d (Cleanup make.kak and optimize
the make-next/make-prev regexes, 2016-12-09). There is one case left
where a filename would theoretically span multiple lines. Fix and
optimize this too.
grep-jump and make-jump[*] support Windows-style paths like C:\path.
However grep-next-match and make-next-error don't, which suggests
that no one uses this feature. IIRC Cygwin mounts Windows drives in
proper Unix paths like /mnt/drive_c.
Let's remove it for simplicity and consistency.
This reverts commit 6c47b204e (Support windows style path in grep
output, 2014-11-11).
[*]: Though make-jump recently regressed in 8e5ca3f21 (rc/make.kak
introduce a new option to be back compatible, 2023-10-27) by failing
to capture the "C:" prefix.
Running an invalid command like "grep -abc" shows no output at all.
Let's give better feedback by showing the error message from grep.
We used to do this until an unrelated change, bd5955c73 (grep: remove
eventual \r, 2013-02-13).
Why?
Most users who pass the current selection to grep likely do not intend to pass
the selection as a regex input string.
This makes the grepcmd use an additional -F flag to perform literal-string
matching for the current selection. The -F flag seems to be the standard flag
for literal-string matching in every grep implementation I've found.
`x` is often criticized as hard to predict due to its slightly complex
behaviour of selecting next line if the current one is fully selected.
Change `x` to use the previous `<a-x>` behaviour, and change `<a-x>` to
trim to fully selected lines as `<a-X>` did.
Adapt existing indentation script to the new behaviour
-verbatim will disable argument parsing in evaluate-commands, making
it possible to forward a single command to a different context without
triggering a reparsing of the arguments.
Fixes -try-client support in grep.kak
