The xfuncname pattern finds func/class declarations
in diffs to display as a hunk header.

This patch adds xfuncname regex and some respective
tests for Kotlin language.

Also modifies `Documentation./gitattributes.txt` to state
the same.

I didn't look at the regexes etc. at a glance, but this is missing the
corresponding tests for the word-diff part of the regexes. It would be
nice to have those tests too.

See the t/t4034/ directory for that (and no, this whole setup isn't very
discoverable, sorry!).
