These printed "Unknown error while evaluating command substitution".
Now they print something like
```
fish: for: status: cannot overwrite read-only variable
for status in foo; end
^~~~~^
in command substitution
fish: Invalid arguments
echo (for status in foo; end)
^~~~~~~~~~~~~~~~~~~~~~~^
```
for `echo (for status in foo; end)`
This is, of course, still not *great*. Mostly the `fish: Invalid
arguments` is basically entirely redundant.
An alternative is to simply skip the error message, but that requires some
more scaffolding (describe_with_prefix adds some error messages on its
own, so we can't simply say "don't add the prefix if we don't have a
message")

After accidentally running a command that includes a pasted password, I want
to delete command from history. Today we need to recall or type (part of)
that command and type "history delete". Let's maybe add a shortcut to do
this from the history pager.
The current shortcut is Shift+Delete. I don't think that's very discoverable,
maybe we should use Delete instead (but only if the cursor is at the end of
the commandline, otherwise delete a char).

* wildcard: Remove file size from the description
We no longer add descriptions for normal file completions, so this was
only ever reached if this was a command completion, and then it was
only added if the file wasn't a regular file... in which case it can't
be an executable.
So this was dead.
* Make possible_link() a maybe
This gives us the full information, not just "no" or "maybe"
* wildcard: Rationalize file/command completions
This keeps the entry_t as long as possible, and asks it, so especially
on systems with working d_type we can get by without a single stat in
most cases.
Then it guts file_get_desc, because that is only used for command
completions - we have been disabling file descriptions for *years*,
and so this is never called there.
That means we have no need to print descriptions about e.g. broken symlinks, because those are not executable.
Put together, what this means is that we, in most cases, only do
an *access(2)* call instead of a stat, because that might be checking
more permissions.
So we have the following constellations:
- If we have d_type:
- We need a stat() for every _symlink_ to get the type (e.g. dir or regular)
(this is for most symlinks, if we want to know if it's a dir or executable)
- We need an access() for every file for executables
- If we do not have d_type:
- We need a stat() for every file
- We need an lstat() for every file if we do descriptions
(i.e. just for command completion)
- We need an access() for every file for executables
As opposed to the current way, where every file gets one lstat whether
with d_type or not, and an additional stat() for links, *and* an
access.
So we go from two syscalls to one for executables.
* Some more comments
* rust link option
* rust remove size
* rust accessovaganza
* Check for .dll first for WSL
This saves quite a few checks if e.g. System32 is in $PATH (which it
is if you inherit windows paths, IIRC).
Note: Our WSL check currently fails for WSL2, where this would
be *more* important because of how abysmal the filesystem performance
on that is.
This makes it so expand_intermediate_segment knows about the case
where it's last, only followed by a "/".
When it is, it can do without the file_id for finding links (we don't
resolve the files we get here), which allows us to remove a stat()
call.
This speeds up the case of `...*/` by quite a bit.
If that last component was a directory with 1000 subdirectories we
could skip 1000 stat calls!
One slight weirdness: We refuse to add links to directories that we already visited, even if they are the last component and we don't actually follow them. That means we can't do the fast path here either, but we do know if something is a link (if we get d_type), so it still works in common cases.

This can be bound like `bind \cl clear-screen`, and is, by default
In contrast to the current way it doesn't need the external `clear`
command that was always awkward.
Also it will clear the screen and first draw the old prompt to remove
flicker.
Then it will immediately trigger a repaint, so the prompt will be overwritten.
(cherry picked from commit c4ca1a68d361c2f0e636c2f5aba53fc0c35a52f1)
This uses "screen.reset_line" to move the cursor without informing the
reader's machinery (because that deals with positions *in the
commandline*), but then only repainted "if needed" - meaning if the
reader thought anything changed.
That could lead to a situation where the cursor stays at column 0
until you do something, e.g. in
```fish
bind -m insert u undo
```
when you press alt+u - because the *escape* calls repaint-mode, which
puts the cursor in column 0, and then the undo doesn't, which keeps it
there.
Of course this binding should also `repaint-mode`, because it changes
the mode.
Some changes might be ergonomic:
1. Make repaint-mode the default if the mode changed (we would need to
skip it for bracketed-paste)
2. Make triggering the repaint easier - do we need to set
force_exec_prompt_and_repaint to false here as well?
Anyway, this

This was introduced as a workaround to #7215 - xdg-open's generic path

This has been fixed a month ago in xdg-open, so we can stop doing it.

(cherry picked from commit 0cdf801d0b979c1aa53310b905791a6514792eef)
This is a sensible thing to do, and fixes some cases where we're
state-dependent.
E.g. this fixes the case in the pager where some things are bold and
some aren't, because that bolding is (rather awkwardly) implicitly
triggered when we have a background, and so we don't notice we need to
re-do that bolding after we moved to the next line because we think we
still have the same color.

This was already supposed to handle `--foo=bar<TAB>` cases, except it
printed the `--foo=` again, causing fish to take that as part of the
token.

(cherry picked from commit b03327f5d2e0c7062f5af13d194e5c989df28c69)
I sometimes find myself doing something like this:
- Look for a commandline that includes "echo" (as an example)
- Type echo, press up a few times
- I can't immediately find what I'm looking for
- Press ctrl-r to open up the history pager
- It uses the current commandline as the search string,
so now I'm looking for "echo foobar"
This makes it so if the search string already is in use, that's what
the history-pager picks as the initial search string.

Without this, a recipe containing a trailing backslash followed by a line not
beginning with tab (like any non-continued recipe lines would) would result in
the continuation showing up in completions.
Whenever a line ends in a backslash, consider the next line invalid as a target.
Regex explanation:
^([^#]*[^#\\])? -- optional prefix not containing comment character and not
ending in backslash
(\\\\)*\\$ -- 2n+1 backslashes at end of line (handles escaped backslashes)

This used to print all codepoints outside of the ASCII range (i.e.
above 0x80) in \uXXXX or \UYYYYYYYY notation.
That's quite awkward, considering that this is about keys that are
being pressed, and many keyboards have actual symbols for these on
them - I have an "ö" key, so I would like to use `bind ö` and not
`bind \u00F6`. So we go by iswgraph.
On a slightly different note, `\e` was written as `\c[ (or \e)`. I do
not believe anyone really uses `\c[` (the `[` would need to
be escaped!), and it's confusing and unnecessary to even mention that.

Note that this will also allow `builtin and`, which is somewhat
useless, but then it is also useless outside of a pipeline.

Unfortunately, /var/lib/dpkg/status on recent-ish Debian versions at
least only contains the *installed* packages, rendering this solution
broken.
What we do instead is:
1. Remove a useless newline from each package, so our limit would now
let more full package data sets through
2. Increase the limit by 5x
This yields a completion that runs in ~800ms instead of ~700ms on a
raspberry pi, but gives ~10x the candidates, compared to the old
apt-cache version.
