This was an issue with "--no-execute", which has no variables and
therefore no $HOME:
```fish
fish --no-execute /path/to/file
```
would say the error is in `~/path/to/file`.
Instead, since this is just for a message, we simply return the
filename without doing the replacement.

This gives us the biggest chance that these are *visible* in the
terminal, which allows people to choose something nicer.
It changes two colors - the autosuggestion and the pager
description (i.e. the completion descriptions in the pager).
In a bunch of terminals I've tested these are pretty similar - for the
most part brblack for the suggestions is a bit brighter than 555, and
yellow for the descriptions is less blue
than the original.
We could also make the descriptions brblack, but that's for later.
Technically we are a bit naughty in having a few foreground and
background pairs that might not be visible,
but there's nothing we can do if someone makes white invisible on brblack.

This didn't work for something like `pactl set-card-profile foo
<TAB>`,
because it didn't allow for the card name, as it would just print the
index again and again.

This allows giving a range like "5..7".
It works in combination with more (including overlapping) ranges or
single indices.

This test wants to generate a U+FDD2 to see it is not mishandled.
To do so, we tried to use sh, which on my system is bash and can do
`$'\ufdd2'`.
Unfortunately on other systems it might be dash, which won't do that.
Since I don't know of a good no-dependency portable way to generate
this (I dimly remember python3 being a shim on some systems, so I do
not want to invoke it here), we'll just use our own printf.
Which is a worse test, we control both parts, but it'll do.

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.
