This was "function", needs to be "function*s*".
It was only an issue in the option parsing because we set cmd there
again instead of passing it. Maybe these should just be file-level constants?
This is an alternative to the very common pattern of
```rust
streams.err.append(output);
streams.err.append1('\n');
```
Which has negative performance implications, see https://github.com/fish-shell/fish-shell/pull/9229
It takes `Into<WString>` to hopefully avoid allocating anew when the argument is
a WString with leftover capacity
This used expect_re with a regex ending in `.*`, followed by an
`expect_prompt`.
This meant that, depending on the timing, the regex could swallow the
prompt marker, which caused extremely confusing output like
>Testing file pexpects/generic.py:Failed to match pattern: prompt 14
> ...
> OUTPUT +1.33 ms (Line 70): \rprompt 13>functions\r\nN_, abbr,
> alias, bg, cd, [SNIP], up-or-search, vared, wait\r\n⏎
> \r⏎ \r\rprompt 14>
Yeah - it shows that "prompt 14" was in the output and it can't find
"prompt 14".
I could reproduce the failure locally when running the tests
repeatedly. I got one after 17 attempts and so far haven't been able
to reproduce it with this change applied.
This removes some spurious unsafe and some imports.
Note: We don't use it in `test`, because that can be asked to check
arbitrary file descriptors, while this only checks stdout specifically.
Turns out doing `==` on Enums with values will do a deep comparison,
including the values.
So EventDescription::Signal(SIGTERM) is !=
EventDescription::Signal(SIGWINCH).
That's not what we want here, so this does a bit of a roundabout thing.
* Simplify and fix `__fish_is_zfs_feature_enabled`
Previously `__fish_is_zfs_feature_enabled` was doing
`<whitespace>$queried_feature<whitespace>` pattern matching which
was skipping the state part expected in the follow-up checking code.
Passing the dataset/snapshot in a `target` argument is pointless. As
none of the existing code attempts to do this plus it is also a
private function (`__` prefix), rename of the argument and removal
of extra text replacement should not be considered a breaking change.
* Changed the `&& \` into `|| return`
* Run `fish_indent`
The `impl<T> Hash for &T` hashes the string itself[^1].
It is unclear if that is actually faster than just calling `keyfunc` multiple times (they should all be linear).
For context, Rust by default uses SipHash 1-3 db1b1919ba
An alternative would be to store it as raw pointers aka `*const T`, which have a cheaper hash impl.
That has a more complicated implementation + removes lifetimes.
This commit rather removes the premature optimization.

- The Err-variants will be used by e.g. wildcard, so might as well change it
now.
- `create_directory` should now not infinitely loop until it fails with an
error message that isn't `EAGAIN`
These are both clearly behind early returns, there is no need to check it again.
This isn't a case where we're doing logic gymnastics to see that it
can't be run without no_exec() being handled, this is
```c++
if (no_exec()) return;
// ..
// ..
// ..
if (no_exec()) foo;
```
We have already run waccess with X_OK. We already *know* the file is
executable.
There is no reason to check again.
Restores some of the speedup from the fast_waccess hack that was
removed to fix#9699.
