Prior to this fix, builtin_eval would direct output to the io_chain of the
job. The problem is with pipes: `builtin_eval` might happily attempt to
write unlimited output to the write end of a pipe, but the corresponding
reading process has not yet been launched. This results in deadlock.
The fix is to buffer all the output from `builtin_eval`. This is not fun
but the best that can be done until we have real concurrent processes.

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
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.

This was a weird one. We split the aliases correctly even with
multiple lines, but then broke it all again when we just printed the
description.
Note that it would be possible to use `string split0` here, but since
anything longer than a line is likely too long for a description
anyway we don't bother.
Fixes#6946.
(cherry picked from commit 1988bd2579)
When this switched over from directly piping commandline to storing
its output and using printf, I inadvertently always added a trailing
newline. That's probably annoying.
Note that this will now always *remove* a trailing newline (because
the command substitution does). That will barely make a
difference (because trailing newlines are quite unusual in the
commandline) and will probably feel better than keeping it - we could
even make a point of removing trailing whitespace in general.

Fixes#6798
This re-adds some false positives: functions, builtins and abbreviations
are suggested after commands like sudo but I don't think anyone had
complained about that.
(cherry picked from commit 2a89873e6d686fcff1d26d0914a8b9f90b7cc308)
Currently we do not add such command lines to the history, so there
won't be a suggestion from history anyway.
Fixes#6763 which occurs because midnight commander feeds fish commands
like this one (note the leading space)
` cd (printf '%b' '\0057home\0057johannes\0057git\0057fish\0055shell\0057build')`
(cherry picked from commit 390647ae34)
The output of
systemctl list-units
seems to include a marker of '●' or '*' for some units, even if the
output is not going to a terminal and "--no-legend" and "--no-pager"
are given. This appears
to be a recent development, and there does not appear to be a flag to
disable it.
So we simply filter it out in the completions to once again hopefully
offer the actual units.
Fixes#6740
Even if $DISPLAY is unset, xdg-open can be useful, and on systems that
have xdg-open, "open" is most likely some god awful outdated thing
called "openvt" elsewhere.
Fixes#6739

If given a prompt that includes a non-ascii char and a C locale, fish
currently fails to properly display it.
So you set `function fish_prompt; echo 😃; end` and it shows empty
space.
While the underlying cause is obviously using a C locale and non-C
characters to begin with, this is an unacceptable failure mode.
Apparently I misunderstood wcstombs, so I inadvertently broke this in
2b0b3d3 while trying to fix 5134949's crash.
Just return the offending bit to pre-5134949 levels, so instead of an
infinite recursion we just call a lame function a couple of times.
This teaches the reader fast-path to use self-insert-notfirst, allowing
it to handle spaces. This greatly increases the performance of paste by
reducing redraws.
Fixes#6603. Somewhat improves #6704
This adds basic support for self-insert-notfirst. When we see a
self-insert-nonempty char event, we kick it back to the outer loop,
which only inserts the character if the cursor is not at the beginning.
This adds a new readline command self-insert-notfirst, which is
analogous to self-insert, except that it does nothing if the cursor
is at the beginning. This will serve as a higher-performance implementation
for stripping leading spaces on paste.
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.

(cherry picked from commit da7b762f4a)
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.

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.
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.
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.
Which happened when starting the selection at the end of the commandline.
In this case, selections still interact weirdly with autosuggestions (the
first character of the suggestion appears to be part of the selection
when it's not).
Fixes#6680
(cherry-picked from commit 99851c09b3)
Since #6406, read will trim whitespace before the last variable.
In this case there is only one variable, and the line looks like
M CHANGELOG.md
so it does indeed start with whitespace, and the whitespace is quite
significant.
Fixes#6650.
