7815cb363c parse_util: Only reject time in a pipeline without decorator
This allows e.g. `foo | command time`, while still rejecting `foo | time`.

(this should really be done in the ast itself, but tbh most of
parse_util kinda should)

Fixes #9985

a7c8e0cdfb Fix #9899 integer overflow in string repeat
We could end up overflowing if we print out something that's a multiple of the
chunk size, which would then finish printing in the chunk-printing, but not
break out early.

72edd888f1 Return a falsey status if the last -c command has a parse error
This makes `fish -c begin` fail with a status of 127 - it already
printed a syntax error so that was weird. (127 was the status for
syntax errors when piping to fish, so we stay consistent with that)

We allow multiple `-c` commands, and this will return the regular
status if the last `-c` succeeded.

This is fundamentally an extremely weird situation but this is the
simple targeted fix - we did nothing, unsuccessfully, so we should
fail.

Things to consider in future:

1. Return something better than 127 - that's the status for "unknown
command"!
2. Fail after a `-c` failed, potentially even checking all of them
before executing the first?

Fixes #9888

037f4b9eea __fish_complete_directories: Remove --foo= from token
Otherwise this would complete

`git --exec-path=foo`, by running `complete -C"'' --exec-path=foo"`,

which would print "--exec-path=foo", and so it would end as

`git --exec-path=--exec-path=foo` because the "replaces token" bit was
lost.

I'm not sure how to solve it cleanly - maybe an additional option to
`complete`?

Anyway, for now this
Fixes #9538.

3bef75fb79 builtins: Don't crash for negative return values
Another from the "why are we asserting instead of doing something

The alternative is to make exit() and return() compute their own exit

e84f588d11 reader: make Escape during history search restore commandline again
Commit 3b30d92b6 (Commit transient edit when closing pager, 2022-08-31)
inadvertently introduced two regressions to history search:

1. It made Escape keeps the selected history entry,
   instead of restoring the commandline before history search.
2. It made history search commands add undo entries.

Fix both of this issues.

572a568268 abbr: Erase the old universal variable with abbr --erase
This means cleaning out old universal variables is now just:

```fish
abbr --erase (abbr --list)
```

which makes upgrading much easier.

Note that this erases the currently defined variable and/or any
universal. It doesn't stop at the former because that makes it *easy*
to remove the universals (no running `abbr --erase` twice), and it
doesn't care about globals because, well, they would be gone on
restart anyway.

3005adebd5 Revert "Remove print_hints from builtin_missing_argument and builtin_unknown_option"
Unfortunately print_hints was true *by default* - so for all builtins
that didn't pass it it would now be false instead.

This resulted in the trailer missing, which includes the line number
and context. So if you ran a script that includes `bind -M` the error
message would now just be "bind: -M: option requires an argument",
with no indication as to where.

This reverts commit 8a50d47a46.

30a37d9433 abbr: Make show output actually work
This would print

```
abbr -a -- dotdot --regex ^\\.\\.+\$ --function multicd
```

which expands "dotdot" to "--regex ^\\.\\.+\$...".

Instead, we move the name to right before the replacement, and move
the `--` before that:

```
abbr -a --regex ^\\.\\.+\$ --function -- dotdot multicd
```

It might be possible to improve that, but this at least round-trips.

35a4688650 Rename abbreviation triggers
This renames abbreviation triggers from `--trigger-on entry` and
`--trigger-on exec` to `--on-space` and `--on-enter`. These names are less
precise, as abbreviations trigger on any character that terminates a word
or any key binding that triggers exec, but they're also more human friendly
and that's a better tradeoff.

1402bae7f4 Re-implement abbreviations as a built-in
Prior to this change, abbreviations were stored as fish variables, often
universal. However we intend to add additional features to abbreviations
which would be very awkward to shoe-horn into variables.

Re-implement abbreviations using a builtin, managing them internally.

Existing abbreviations stored in universal variables are still imported,
for compatibility. However new abbreviations will need to be added to a
function. A follow-up commit will add it.

Now that abbr is a built-in, remove the abbr function; but leave the
abbr.fish file so that stale files from past installs do not override
the abbr builtin.

892a820672 Make sure that cd to a relative CDPATH results in absolute $PWD
We have had multiple crashes for relative CDPATH entries.  Commit 5e274066e
(Always return absolute path in path_get_cdpath, 2019-10-17) tried to fix
all of them but it failed to do justice to its title.  Let's fix this to
actually return absolute paths, always.  Take care to to normalize the path
because it is used for autosuggestions. The normalization is mostly relevant
for CDPATH=. (the default) but it doesn't hurt others.

c4a60feff1 Stop attempting to complete inside comments
Inside a comment we offer plain file completions (or command completions if
the comment is in command position). However these completions are broken
because they don't consider any of the surrounding characters. For example
with a command line

    echo # comment
              ^ cursor

we suggest file completions and insert them as

    echo # comsomefile ment

Providing completions inside comments does not seem useful and it can be
misleading. Let's remove the completions; this should communicate better that
we are in a free-form comment that's not subject to fish syntax.

4cb19e244b Sort and deduplicate output of complete -C
This addresses a long-standing TODO where `complete -C` output isn't
deduplicated.

With this patch, the same deduplication and sort procedure that is run on actual
pager completions is also executed for `complete -C` completions (with a `-C`
payload specified).

This makes it possible to use `complete -C` to test what completions will
actually be generated by the completions pager instead of it displaying
something completely divorced from reality, improving the productivity of fish
completions developers.

Note that completions that wouldn't be shown in the pager are also omitted from
the results, e.g. `test/buildroot/` and `test/fish_expand_test/` are omitted
from the check matches in `checks/complete_directories.fish` because even if
they were generated, the pager wouldn't have shown them. This again makes
reasoning about and debugging completions much easier and more sane.

52dcfe11af Make \x the same as \X
Up to now, in normal locales \x was essentially the same as \X, except
that it errored if given a value > 0x7f.

That's kind of annoying and useless.

A subtle change is that `\xHH` now represents the character (if any)
encoded by the byte value "HH", so even for values <= 0x7f if that's
not the same as the ASCII value we would diverge.

I do not believe anyone has ever run fish on a system where that
distinction matters. It isn't a thing for UTF-8, it isn't a thing for
ASCII, it isn't a thing for UTF-16, it isn't a thing for any extended
ASCII scheme - ISO8859-X, it isn't a thing for SHIFT-JIS.

I am reasonably certain we are making that same assumption in other
places.
