The default hg prompt is slow on large repositories (hg status takes
2-3 seconds on mozilla-central) which is unacceptable as a default.
Mimick our git prompt: by default, only show the current branch.
If the new variable $fish_prompt_hg_show_informative_status is set,
then use the old behavior.

debounce_t will be used to limit thread creation from background highlighting
and autosuggestion scenarios. This is a one-element queue backed by a
single thread. New requests displace any existing queued request; this
reflects the fact that autosuggestions and highlighting only care about
the most recent result.
A timeout allows for abandoning hung threads, which may happen if you
attempt to e.g. access a dead hard-mounted NFS server. We don't want
this to defeat autosuggestions and highlighting permanently, so allow
spawning a new thread after the timeout (here 500 ms).
The problem is that under TSAN, the timing of signals becomes very weird and
exposes some real race conditions. We will need to re-design how signal
event handlers work.
bbc3fecbe introduced a regression where support for 256 color was not
detected on xterm-like terminals that did not define the TERM_PROGRAM
env variable. Almost no terminal on linux define this variable.
This test launches two background processes and is sensitive to
interleaving of output. Fix it so that newlines are not output by
the background process.
Hopefully this fixes the flakiness of this test.
55e3270 introduced a regression where we would remove all completed
jobs. But jobs that want to print a status message get skipped, so
the status message (and associated event handlers) might not get run.
Fix this by making it explicit which jobs are safe to process, and which
should be skipped.
Fixes#6679.
f8ba0ac5bf introduced a bug where INT handlers would themselves be
cancelled, due to the signal. Defer processing handlers until the
parser is ready to execute more fish script.
Fixes the interactive case of #6649.
This was written before local-exported variables did anything useful.
Passing these vars as local-exports removes the need to define the
validation function with `--no-scope-shadowing` which is quite the
hack.
This is apparently quite slow on large svn repos (like 40 seconds
slow), and we don't have a good thing to display other than the full
file information.
So we'll have to disable it for now.
Fixes#6681.

If a background process runs a fish function which launches another
background process, ensure that these background procs get different
pgroups. Add a test for it.
