Also add completions, changelog entry, adjust documentation, add examples with emoji and some tests. Apply some minor style nitpicks and avoid extra allocations of the input strings.

Let visible length work with CR and LF Because we are, ultimately, interested in how many cells a string occupies, we *have* to handle carriage return (`\r`) and line feed (`\n`). A carriage return sets the current tally to 0, and only the longest tally is kept. The idea here is that the last position is the same as the last position of the longest string. So: abcdef\r123 ends up looking like 123def which is the same width as abcdef, 6. A line feed meanwhile means we flush the current tally and start a new one. Every line is printed separately, even if it's given as one. That's because, well, counting the width over multiple lines doesn't *help*. As a sidenote: This is necessarily imperfect, because, while we may know the width of the terminal ($COLUMNS), we don't know the current cursor position. So we can only give the width, and the user can then figure something out on their own. But for the common case of figuring out how wide the prompt is, this should do.

Run fish_indent on all our fish scripts It's now good enough to do so. We don't allow grid-alignment: ```fish complete -c foo -s b -l barnanana -a '(something)' complete -c foo -s z -a '(something)' ``` becomes ```fish complete -c foo -s b -l barnanana -a '(something)' complete -c foo -s z -a '(something)' ``` It's just more trouble than it is worth. The one part I'd change: We align and/or'd parts of an if-condition with the in-block code: ```fish if true and false dosomething end ``` becomes ```fish if true and false dosomething end ``` but it's not used terribly much and if we ever fix it we can just reindent.

string: Allow `collect --allow-empty` to avoid empty ellision (#8054) * string: Allow `collect --no-empty` to avoid empty ellision Currently we still have that issue where test -n (thing | string collect) can return true if `thing` doesn't print anything, because the collected argument will still be removed. So, what we do is allow `--no-empty` to be used, in which case we print one empty argument. This means test -n (thing | string collect -n) can now be safely used. "no-empty" isn't the best name for this flag, but string's design really incentivizes reusing names, and it's not *terrible*. * Switch to `--allow-empty` `--no-empty` does the exact opposite for `string split` and split0. Since `-a`/`--allow-empty` already exists, use it.

string: Quit early if --quiet is satisfied E.g. if we do `string match -q`, and we find a match, nothing about the input can change anything, so we quit early. This is mainly useful for performance, but it also allows `string` with `-q` to be used with infinite input (e.g. `yes`). Alternative to #7495.

Add `string` to reserved keywords Since `string match` now creates variables, wrapping `string` necessarily breaks things, so we need to disallow it. See #7459, #7509.

# `string` can't be wrapped properly anymore, since `string match` creates variables:
function string
builtin string $argv
end

escape_string_script: Escape DEL as \x7f This used to print a literal DEL character in the output for `bind`, which wouldn't actually show up and made it hard to figure out what the key was. So we just escape it back to how we actually used it - `\x7f`. Fixes #7631.

string: Add "--groups-only" to match This adds a simple way of picking bits from a string that might be a bit nicer than having to resort to a full `replace`. Fixes #6056
