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)

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.
(cherry picked from commit 6325b3662d)
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?

(cherry picked from commit a6c36a014c)
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

Another from the "why are we asserting instead of doing something
sensible" department.
The alternative is to make exit() and return() compute their own exit
code, but tbh I don't want any *other* builtin to hit this either?

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.
Inadvertently broken in a2d816710f,
this made `cd .` no longer offer `cd ../` (same for general file completions
like `ls .`, which only offers dotfiles)
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.
Fixes#9468.
This now means `abbr --add` has two modes:
```fish
abbr --add name --function foo --regex regex
```
```fish
abbr --add name --regex regex replacement
```
This is because `--function` was seen to be confusing as a boolean flag.
Example output from a Cirrus bionic-asan-clang run:
```
fish: Unknown command: man
/tmp/cirrus-ci-build/share/functions/__fish_man_page.fish (line 30):
if man "$maincmd" &>/dev/null
^~^
in function '__fish_man_page'

[I] prompt 9>echo TEXThrAi
[I] prompt 9>echo TEXThrAi

```
Yes, this detected escape, waiting *300ms* and then "h" as being below
the escape timeout of 120ms.
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.
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.
Historical behavior is to stop option parsing at the first non-option argument.
Since we have added more options, it seemed impractical to keep that behavior.
However people are using options in their abbr expansions ("abbr e emacs
-nw"). To support this, we ignore options. However, we only ignore them
if they are not valid "abbr" options. Let's ignore all options in the
expansion definition, which is a small price to pay to keep most existing
configurations working.
Fixes#9410
This does not fix other cases which used to work, like
abbr x -unknown
Those are hopefully not used by anyone, so I don't think we need to maintain
support for that.
Also default the marker to '%'. So you may write:
abbr -a L --position anywhere --set-cursor "% | less"
or set an explicit marker:
abbr -a L --position anywhere --set-cursor=! "! | less"
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.
set-cursor enables abbreviations to specify the cursor location after
expansion, by passing in a string which is expected to be found in the
expansion. For example you may create an abbreviation like `L!`:
abbr L! --position anywhere --set-cursor ! "! | less"
and the cursor will be positioned where the "!" is after expansion, with
the "| less" appearing to its right.
This adds support for the `--function` option of abbreviations, so that the
expansion of an abbreviation may be generated dynamically via a fish
function.
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.
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.
Closes#9407
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.

Like the pexpect-based pager compeltions test `complete-group-order.py`, but for
the `complete` builtin. Verifies the same sort/dedup rules that apply to the
pager are also applied to the output of `complete` and asserts the sort behavior
for multiple `complete -k` calls for the same command and with the same (or with
both passing) preconditions.
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.
Fixes ommitted newline char shown after complete -n'(foo)'

Ensure that multiple `-k` completions intermixed with one or more non-`-k`
completions are produced in the expected order with the order of all completions
in a single `-k` completion respected, non-`-k` completions correctly sorted and
interspersed, and the results of multiple `-k` completions in the
reverse-intuitive order (with chronologically later completions coming before
chronologically earlier `-k` counterparts), as per #9221.
