Since we enable/disable terminal protocols whenever we pass terminal ownership,
tests can no longer run in parallel on the same terminal.
For the same reason, readline shortcuts in the gdb REPL will not work anymore.
As a remedy, use gdbserver, or lobby for CSI u support in libreadline.
Add sleep to some tests, otherwise they fall (both in CI and locally).
There are two weird failures on FreeBSD remaining, disable them for now

Design and implementation borrows heavily from Kakoune.
In future, we should try to implement more of the kitty progressive
enhancements.
Closes#10359
To do so add an ad-hoc "commandline --search-field" to operate on pager
search field.
This is primarily motivated because a following commit reuses the
fish_clipboard_paste logic for bracketed paste. This avoids a regression.
Terminal titles are set with an OSC 0 sequence. I don't think we want to
support terminals that react badly to unknown OSC (or CSI) sequences.
So let's remove our feature detection.
This will fix future false negatives along the lines of
https://github.com/fish-shell/fish-shell/pull/10037
This binding is akin to ForwardSingleChar but it is "passive" in that is not
intended to affect the meta state of the shell: autocompletions are not accepted
if the cursor is at the end of input and it does not have any effect in the
completions pager.
Currently, we expand command-abbrs (those with `--position command`) after `if`, but not after `command` or `builtin` or `time`:
```fish
abbr --add gc "git checkout"
```
will expand as `if gc` but not as `command gc`.
This was explicitly tested, but I have no idea why it shouldn't be?
The incorrect order of operations was being used since && binds tighter than ||
in rust (as with most sane languages).
Under Linux, EAGAIN == EWOULDBLOCK so this would always succeed in the case of a
non-blocking fd without making the call to make_fd_nonblocking().
Comparing to the 3.7.0 C++ code, it looks like this was an oversight introduced
in the migration to rust.
In particular, this allows restoring the terminal on crashes, which is
feasible now that we have the panic handler. Since std::process::exit() skips
destructors, we need to reshuffle some code. The "exit_without_destructors"
semantics (which std::process::exit() als has) was mostly necessary for C++
since Rust leaks global variables by default.
When fish crashes due to a panic, the terminal window is closed. Some
terminals keep the window around when the crash is due to a fatal signal,
but today we don't exit via fatal signal on panic.
There is the option to set «panic = "abort"» in Cargo.toml, which
would give us coredumps but also worse stacktraces on stderr.
More importantly it means that we don't unwind, so destructors are skipped
I don't think we want that because we should use destructors to
restore the terminal state.
On crash in interactive fish, read one more line before exiting, so the
stack trace is always visible.
In future, we should move this "read one line before exiting" logic to where
we call "panic!", so I can attach a debugger and see the stacktrace.
Looks like "add_custom_command(OUTPUT ...)" assumes the dependencies are
correct which is not always true. We can use "add_custom_target" to always
re-run Cargo.
Unfortunately on Debian "open" is a symlink to "openvt", and there's
no way from outside to tell.
This prevents fish from failing because no browser could be found.
