4e4852c40a history: Improve bash import check
- Check for special characters *before* attempting to parse
- Also ignore lines with `{` and `*`
- Also skip lines with `<<` because that might be a heredoc (or a
- `<<<` herestring)

Fixes #7874.

b44f40547b Rationalize exit codes for failed execs
This cleans up some exit code processing. Previously a failed exec
would produce exit code 125 unconditionally, while a failed posix_spawn
would produce exit code 1 (!).

With this change, fish reports exit code 126 for not-executable, and 127
for file-not-found. This matches bash.

3255999794 Bravely set job control to full at startup
We have no idea why this was even a thing. For now simply set it to
"all"/"full" (why these two names? no idea) at startup and allow
changing it later.

Settting it *immediately* when defining the variable sets it too soon
because we don't have the interactive signal handlers
enabled (including the one for SIGTTOU), so let's first settle for
this little piece of awkwardness.

This needs widespread testing, so we merge it early, immediately after
the release.

c55865f76e Change use of tmux's resize-window to resize-pane
I believe they are both equivalent for our particular purpose, since we
only care about enforcing the size fish sees.

`resize-window` was only introduced in tmux 2.9, which isn't available
at least on Ubuntu 18.04 LTS (currently using tmux 2.6) and probably
many others.

(Clever idea to use tmux here!)

Use the correct case in completion pager (#7744)
Consider

	$ complete -c foo -a 'aab aaB' -f
	$ foo A<TAB>

since 28d67c8 we would insert the common prefix AND show the pager.
Due to case-insensitive comparison, "b/B" was considered to be part
of the prefix. Since the prefix is added to each pager item [1]
we get wrong results. Fix this by removing the insensitive comparison
between completions - I don't think it was of much use anyway.
Commandline tokens are still matched case-insensitively, this is
just about completions.

Test this by running interactive fish inside tmux (pexpect's terminal
emulation not have enough capabilities).  Also add tests for recent
interactive regressions #7526 and #7738.

Closes #3978

[1]: b38a23a would solve this differently by giving every pager item
its own prefix, but was reverted since it needs more fixes.

d79f864072 Add a note for help thing to the missing doc error message
This should cover most cases - the user didn't install the docs and is
trying to view the man page via __fish_print_help, so we don't have a
way to show anything.

But `help thing` will fall back to the online version of the docs,
which should work if there's an internet connection.

3cb105adbd Restore terminal modes after running key bindings with external commands
This concerns the behavior when running an external command from a key
binding. The history is:

Prior to 5f16a299a7, fish would run these external commands in shell
modes. This meant that fish would pick up any tty changes from external
commands (see #2114).

After 5f16a299a7, fish would save and restore its shell modes around
these external commands. This introduced a regression where anything the
user typed while a bound external command was executing would be echoed,
because external command mode has ECHO set in c_lflag. (This can be
reproed easily with `bind -q 'sleep 1'` and then pressing q and typing).
So 5f16a299a7 was reverted in fd9355966.

This commit partially reverts fd9355966. It has it both ways: external
commands are launched with shell modes, but/and shell modes are restored
after the external command completes. This allows commands to muck with
the tty, as long as they can handle getting shell modes; but it does not
enable ECHO mode so it fixes the regression found in #7770.

Fixes #7770. Fixes #2114 (for the third time!)

This partially reverts commit fd9355966e.

fd9355966e Stop donating the terminal for bind functions
Unfortunately this causes input coming in while bind functions are

Since the cure is worse than the disease let's just stop doing it.

My guess is this needs to *only* be done while running an external
command.

4762d52e52 output: A background is set if it's not a special non-color
For reasons unclear to me, fish enables bold mode unconditionally if
the background is set.

However, this called a background "set" if it wasn't exactly the
"normal" color, whereas set_color --print-colors would set a color
of *none*.

We have three special non-color colors:

- "normal"
- "reset"
- "none"

All of these specify some form of absence of background color, so all
of them should be checked.

Rewrite the real file if history file is a symlink (#7754)
* Rewrite the real file if history file is a symlink

When the history file is a symbolic link, `fish` used to overwrite
the link with a real file whenever it saved history. This makes
it follow the symlink and overwrite the real file instead.

The same issue was fixed for the `fish_variables` file in 622f2868e
from https://github.com/fish-shell/fish-shell/pull/7728.
This makes `fish_history` behave in the same way. The implementation
is nearly identical.

Since the tests for the two issues are so similar, I combined them
together and slightly expanded the older test.

This also addresses https://github.com/fish-shell/fish-shell/issues/7553.

* Add user-facing error when history renaming fails

Currently, when history file renaming fails, no message is shown to the
user. This happens, for instance, if the history file is a symlink
pointing to another filesystem.

This copies code (with a bit of variation, after reviewer comments) from

589eb34571/src/env_universal_common.cpp (L486-L491)

into `history.cpp`, so that a message is shown to the user.

8a07db8e8f Revert "Revert "Speed up check-all-fish-files when executed locally""
This reverts commit e240d81ff8 and
introduces a more compatible method of finding newly added fish scripts
to syntax check.

`find -newer` is the original and is supported by everything under the
sun (including FreeBSD, NetBSD, Solaris, OpenIndiana, macOS 10.10, WSL,
and more), and if not, the tests will succeed anyway. `find -mnewer` was
added later around the time `find -cnewer` and co (which checks the
creation date rather than the modification date) was introduced, but
apparently the GNU version of coreutils never introduced the `-mnewer`
alias for `-newer`.

Yes, this is hacky and yes it would be ideal if the build system is the
one that picked which tests to run rather than the test itself picking.
But let's not pretend that our tests are idealogically ideal or pure
right now and until we fix the mess that is our CMake test integration
(e.g. use ctest and configure each test to be run separately with
configurable payloads, etc) eight seconds is still eight seconds, and
again, the CI isn't affected.

e240d81ff8 Revert "Speed up check-all-fish-files when executed locally"
My find (GNU findutils 4.8.0) prints

> find: unknown predicate `-mnewer'

So we would have to test for support.

Also this is *super* hacky - tests aren't supposed to keep files
around, this is something you would do in the build system.

ddd0e28b4f Speed up check-all-fish-files when executed locally
Only check fish files that have been modified since the last time they
were checked. (This continues with the assumption that we are testing
for broken /usr/share fish scripts and not breakage of the fish parser,
which is covered by all the other tests.)

This saves 8 seconds on an NVMe disk under WSL. Won't affect integrity
of CI runs, which start with a blank slate each time.

d85bdf120f fish_add_path: Handle moving multiple arguments correctly
This `set -e` had a cartesian product that caused it to remove the

old-*third* which is now the second.

11a373f121 Prevent redirecting internal processes to file descriptors above 2
The user may write for example:

    echo foo >&5

and fish would try to output to file descriptor 5, within the fish process
itself. This has unpredictable effects and isn't useful. Make this an
error.

Note that the reverse is "allowed" but ignored:

    echo foo 5>&1

this conceptually dup2s stdout to fd 5, but since no builtin writes to fd
5 we ignore it.

c0af8dae20 fish_indent: fix extra indent of continuation lines inside blocks
fish_indent used to increment the indentation level whenever we saw an escaped
newline.  This broke because of recent changes to parse_util_compute_indents().
Since parse_util_compute_indents() function already indents continuations
there is not much to do for fish_indent - we can simply query the indentation
level of the newline.  Reshuffle the code since we need to pass the offset
of the newline. Maybe this can even be simplified further.

5a0aa7824f Saturate exit codes to 255 for all builtins
After commit 6dd6a57c60, 3 remaining
builtins were affected by uint8_t overflow: `exit`, `return`, and
`functions --query`.

This commit:
- Moves the overflow check from `builtin_set_query` to `builtin_run`.
- Removes a conflicting int -> uint8_t conversion in `builtin_return`.
- Adds tests for the 3 remaining affected builtins.
- Simplifies the wording for the documentation for `set --query`.
- Does not change documentation for `functions --query`, because it does
  not state the exit code in its API.
- Updates the CHANGELOG to reflect the change to all builtins.
