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.
