This matches what we do in --profile's output:
```
> source /home/alfa/.config/fish/config.fish
--> set -gx XDG_CACHE_HOME /home/alfa/.cache
--> set -gx XDG_CONFIG_HOME /home/alfa/.config
--> set -gx XDG_DATA_HOME /home/alfa/.local/share
```
instead of
```
+ source /home/alfa/.config/fish/config.fish
+++ set -gx XDG_CACHE_HOME /home/alfa/.cache
+++ set -gx XDG_CONFIG_HOME /home/alfa/.config
+++ set -gx XDG_DATA_HOME /home/alfa/.local/share
```
This increases a 100ms timeout to 200ms, because we've hit it on
Github Actions:
```
INPUT 3904.65 ms (Line 223): set -g fish_escape_delay_ms 100\n
OUTPUT +1.74 ms (Line 224): \rprompt 25>
INPUT +0.71 ms (Line 230): echo abc def

OUTPUT +2.41 ms (Line 234): \r\ndef abc\r\n

INPUT +0.75 ms (Line 239): echo ghi jkl
INPUT +0.57 ms (Line 240): \x1b

```
In other places it decreases sleeps where we just wait for a timeout to elapse, in which case we don't need much longer than the timeout.
Prior to this change, if fish were launched connected to a tty but not as
pgroup leader, it would attempt to become pgroup leader only if
--interactive is explicitly passed. But bash will unconditionally attempt
to become pgroup leader if launched interactively. This can result in
scenarios where fish is running interactively but in another pgroup. The
most obvious impact is that control-C will result in the pgroup leader
(not fish) exiting and make fish orphaned.
Switch to matching the bash behavior here - we will always try to become
pgroup leader if interactive.
Fixes#7060.
And again clang-format does something I don't like:
- if (found != end && std::strncmp(found->name, name, len) == 0 && found->name[len] == 0) return found;
+ if (found != end && std::strncmp(found->name, name, len) == 0 && found->name[len] == 0)
+ return found;
I *know* this is a bit of a long line. I would still quite like having
no brace-less multi-line if *ever*. Either put the body on the same
line, or add braces.

At least on Arch Linux, pacmd and pulseaudio aren't necessarily available just because pactl is (pipewire is now a thing, and it installs libpulse but not pulseaudio)
When building from source, there is a warning:
../doc_src/cmds/string-match.rst:13: WARNING: Inline emphasis
start-string without end-string.
One fix appears to be putting a space after the epmhasized 'n' character,
e.g., `*n* th` instead of `*n*th`.
When globbing, we have a base directory (typically $PWD) and a path
component relative to that. As PWD is "virtual" it may be a symlink. Prior
to this change we would use wrealpath to resolve symlinks before opening
the directory during a glob, but this call to wrealpath consumed roughly
half of the time during globbing, and is conceptually unnecessary as
opendir will resolve symlinks for us.
Remove it. This may have funny effects if the user's PWD is an unlinked
directory, but it roughly doubles the speed of a glob like `echo ~/**`.
This adds the ability to limit how many expansions are produced. For
example if $big contains 10 items, and is Cartesian-expanded as
$big$big$big$big... 10 times, we would naviely get 10^10 = 10 billion
results, which fish can't actually handle. Implement this in
completion_receiver_t, which now can return false to indicate an overflow.
The initial expansion limit 'k_default_expansion_limit' is set as 512k
items. There's no way for users to change this at present.
This switches certain uses from just appending to a list to using
completion_receiver_t, in preparation for limiting how many completions
may be produced. Perhaps in time this could also be used for "streaming"
completions.
completion_receiver_t wraps a completion list; it will centralize logic
around adding completions and most importantly it will enforce that we
do not exceed our expansion limit.
The pager cleanup missed that the existing token could already include active (as in unescaped) expansions, and just escaped them all.
This means things like `ls ~/<TAB>` would escape the `~`, which is obviously wrong and makes it awkward to use.
This reverts commit b38a23a46d.
I fully expect that we'll try again, but there's no use in keeping master broken while that happens.
Fixes#7526.
E.g. if we do `string match -q`, and we find a match, nothing about
the input can change anything, so we quit early.
This is mainly useful for performance, but it also allows `string`
with `-q` to be used with infinite input (e.g. `yes`).
Alternative to #7495.
warn_unused_result is the persistent one that won't go away with a
simple `(void)write(...)` and needs to be assigned to a variable (that
must then also be declared unused or else you'll get a warning about
_that_).
"smartcase" performs case-insensitive matching if the input string is all
lowercase, and case-sensitive matching otherwise. When completing e.g.
files, we will now show both case sensitive and insensitive completions if
the input string does not contain uppercase characters.
This is a delicate fix in an interactive component with low test coverage.
It's likely something will regress here.
Fixes#3978
