If the padding is not divisible by the char's width without remainder,
we pad the remainder with spaces, so the total width of the output is correct.
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.

This makes history searches case-insensitive, unless the search string
contains an uppercase character.
This is what vim calls "smartcase".
Fixes#7273.
Now command, jobs, type, abbr, builtin, functions and set take `-q` to
query for existence, but the long option is inconsistent.
The first three use `--quiet`, the latter use `--query`. Add `--query`
to the first three, but keep `--quiet` around.
Fixes#7276.
The line offset of a trailing newline on the commandline was computed incorrectly.
As a result, up-arrow did not work for a commandline like the one inserted by:
commandline -i echo '' ''
Note this and the previous commit in the changelog.
This can be used to determine whether the previous command produced a real status, or just carried over the status from the command before it. Backgrounded commands and variable assignments will not increment status_generation, all other commands will.
This pulls in widechar_width.h from commit 7e9dfdaf05059b3f. The big change
here is that some characters which were previously marked as widened in 9
are now marked as unconditionally narrow; this includes some randoms like
hot pepper (U+1F336) but more importantly all of the regional indicators,
which affects how flags are rendered.
If you put two regional indicators together, you get a flag emoji. It's
unclear what the width of this flag emoji should be; Terminal and iTerm2
renders it as width 1, while kitty renders it as width 2. This is
unaffected by fish_emoji_width because the flag does not have an assigned
codepoint, it is a pair of codepoints.
The regional indicators are marked as "neutral" in EastAsianWidth.txt which
means they conceptually have width 1. So two of them have width 2. So now
we assume that flags are rendered as width 2.
This fixes#7237, for terminals that render flags as width 2 (but not 1,
unfortunately, which includes iTerm2 and Terminal.app).
fish_color_match is a variable which controls syntax highlighting for
matching quotes and parens, but only with interactive `read` with shell
highlighting disabled. It seems unlikely that anybody cares about this.
builtins output to stdout and stderr via io_streams_t. Prior to this fix, it
contained an output_stream_t which just wraps a buffer. So all builtin output
went to this buffer (except for eval).
Switch output_stream_t to become a new abstract class which can output to a
buffer, file descriptor, or nowhere. This allows for example `string` to stream
its output as it is produced, instead of buffering it.
