A long standing issue is that bindings cannot mix special input functions
and shell commands. For example,
bind x end-of-line "commandline -i x"
silently does nothing. Instead we have to do lift everything to shell commands
bind x "commandline -f end-of-line; commandline -i x"
for no good reason.
Additionally, there is a weird ordering difference between special input
functions and shell commands. Special input functions are pushed into the
the queue whereas shell commands are executed immediately.
This weird ordering means that the above "bind x" still doesn't work as
expected, because "commandline -i" is processed before "end-of-line".
Finally, this is all implemented via weird hack to allow recursive use of
a mutable reference to the reader state.
Fix all of this by processing shell commands the same as both special input
functions and regular chars. Hopefully this doesn't break anything.

Multiline search strings are weirdly broken (inserting control characters
in the command line) and probably not very useful anyway.
On the other hand I often want to compose a multi-line command
from single-line commands I ran previously.
Let's support this case by limiting the initial search string to the current
line; and replace only that line.
Alternatively this could operate on jobs (that is, replace a surrounding
"foo | bar") instead of using line boundaries.
This is resistant to misuse by including O_DIRECTORY in the open flags and it is
a separate function from {w,}open_cloexec() in preparation for making that one
return a `File` instead of an `OwnedFd`.
`intersects()` is "any of" while `contains()` is "all of" and while it makes no
difference when testing a single bit, I believe `contains()` is less brittle
for future maintenance and updates as its meaning is clearer.

More work in prep for having wopen_cloexec() return `File` directly.
This eliminates checking for an invalid fd and makes both ownership and
mutability clear (some more operations that involve changes to the underlying
state of the fd now require `&mut File` instead of just a `RawFd`).
Code that clearly does not use non-blocking IO is ported to use
`Write::write_all()` directly instead of our rusty port of the `write_loop()`
function (which handles EAGAIN/EWOULDBLOCK in addition to EINTR, while
`write_all()` only handles the latter).
This is a step towards converting `wopen_cloexec()` to return `File` instead of
`OwnedFd`/`AutocloseFd`.¹
In addition to letting us use native standard library functions instead of
unsafe libc calls, we gain additional semantic safety because `File` operations
that manipulate the state of the fd (e.g. `File::seek()`) require a `&mut`
reference to the `File`, whereas using `RawFd` or `OwnedFd` everywhere leaves us
in a position where it's not clear whether or not other references to the same
fd will manipulate its underlying state.
¹ We actually wouldn't even need `wopen_cloexec()` at all (just a widechar
wrapper) as Rust's native `File::open()`/`File::create()` functionality uses
`FD_CLOEXEC` internally.

I was able to trigger this by flipping around the history pager.
Since the only applicable caller here already stops if it gets None,
just don't assert.
I don't think the existing logic is correct, as the comment says, our internal
state is only matched if we *actually* wrote out the file. But if we ran into an
error, it doesn't match, does it?
The incompatible_msrv one is a false positive because we have polyfills for
is_some_and() and is_ok_or() which are Rust 1.74. I'm not yet sure how to
communicate that to Clippy.
Call fish_should_add_to_history to see if a command should be saved
If it returns 0, it will be saved, if it returns anything else, it
will be ephemeral.
It gets the right-trimmed text as the argument.
If it doesn't exist, we do the historical behavior of checking for a
leading space.
That means you can now turn that off by defining a
`fish_should_add_to_history` that just doesn't check it.

The existing logic did not work because:
- Path::new("/foo/bar").ends_with("/bar") does not return true.
- PathBuf::shrink_to() only (potentially) reallocates the backing
storage, and won't have an effect on the stored value.
As mentioned in the comment the historical behavior is because pressing unknown
control characters like Ctrl+4 inserts confusing characters, so let's back
out that part of b77d1d0e2 (Stop crashing on invalid Unicode input, 2024-02-27).
We still have the code for rendering control characters, for pasted text,
or text recalled from history. It is unclear whether we should strip those.
Some terminals already strip control characters from pasted text -- but not
all of them: see https://codeberg.org/dnkl/foot/pulls/312 for example which
has a follow up called "Don't strip HT when pasting in non-bracketed mode".
Don't force the internal use of `RefCell<T>`, let the caller place that into
`MainThread<>` manually. This lets us remove the reference to `MainThread<>`
from the definition of `Screen` again and reduces the number of
`assert_is_main_thread()` calls.
Fairly straightforward, with the only unfortunate part of this being that
`Screen` isn't as pure and now encodes the facte that we use it with
main-thread-only stdout `Outputter`.
The regex struct is pretty large at 560 bytes, with the entire
Abbreviation being 664 bytes.
If it's an "Option<Regex>", any abbr gets to pay the price. Boxing it
means abbrs without a regex are over 500 bytes smaller.
