This should cover all filetypes that already auto-insert comments,
except for rust.kak, which is left for a follow-up.
Most of these are straightforward, some explanation for special cases:
rc/filetype/zig.kak rc/filetype/cue.kak
These indent hooks used their own logic to indent after "{" only if
no comment was inserted. Replace this logic by checking if a comment
was inserted. This works because these "*-insert" hooks are run
before their respective "*-indent" hooks.
rc/filetype/php.kak
This also has some logic to insert "*" after "/*" lines. Basic
usage seems to work still. In future this should borrow from the
c-family one, which works a bit better.
This adds highlighting for
- quoting operators qw, qr, and qx, like `qw< some words >`
- angle brackets after a quoting operator, like `q<string>`
- punctuation as quoting delimiter, like `q|string|`
- POD sections, which start with ^=\w and and with ^=cut
- heredocs; the marker can be a bare word, or a quoted word, like
print <<~ 'EOF'
single quoted heredoc
EOF
Closes#3736
No attempt is made to use different highlighting for interpolated (qq or
"") strings just yet. Recognizing quote boundaries is more important.
This commit allows using the <semicolon> expansion in commands, instead
of `\;`.
It makes commands look more elegant, and prevents new-comers from
falling into the trap of using <a-;> without escaping the semicolon.
