Extended & human-friendly keys See the changelog additions for user-visible changes. Since we enable/disable terminal protocols whenever we pass terminal ownership, tests can no longer run in parallel on the same terminal. For the same reason, readline shortcuts in the gdb REPL will not work anymore. As a remedy, use gdbserver, or lobby for CSI u support in libreadline. Add sleep to some tests, otherwise they fall (both in CI and locally). There are two weird failures on FreeBSD remaining, disable them for now https://github.com/fish-shell/fish-shell/pull/10359/checks?check_run_id=23330096362 Design and implementation borrows heavily from Kakoune. In future, we should try to implement more of the kitty progressive enhancements. Closes #10359

Revert "Revert "Enable job-control in pipeline-pgroup test"" This reverts commit c9f450a93eb19c2e2d641dc93d26975990909143. Puts back job-control in this test.

Run fish_indent on all our fish scripts It's now good enough to do so. We don't allow grid-alignment: ```fish complete -c foo -s b -l barnanana -a '(something)' complete -c foo -s z -a '(something)' ``` becomes ```fish complete -c foo -s b -l barnanana -a '(something)' complete -c foo -s z -a '(something)' ``` It's just more trouble than it is worth. The one part I'd change: We align and/or'd parts of an if-condition with the in-block code: ```fish if true and false dosomething end ``` becomes ```fish if true and false dosomething end ``` but it's not used terribly much and if we ever fix it we can just reindent.

Thread pgroups into command substitutions Give string expansion an (optional) parent pgroup. This is threaded all the way into eval(). This ensures that in a mixed pipeline like: cmd | begin ; something (cmd2) ; end that cmd2 and cmd have the same pgroup. Add a test to ensure that command substitutions inherit pgroups properly. Fixes #6624

# CHECK: All pgroups agreed
# Here everything should live in fish's pgroup.
# Unfortunately we don't know what fish's pgroup is (it may not be fish's pid).
# So run it twice and verify that everything agrees; this implies that it could
# not have used any of the pids of the child procs.

Thread pgroups into builtin_eval Ensure that if eval is invoked as part of a pipeline, any jobs spawned by eval will have the same pgroup as the parent job. Partially fixes #6806

Reenable pgroup eval test in more robust form This re-enables the test that eval retains pgroups, from #6806. The old version was racey and failed a lot. In the new version, we use temp files to resolve the race.
