A feature I have been missing often has been the possibility to limit
grep (and ls-files) to certain filenames.
Say:
git grip -e DEBUG 'Kconfig*'

I usually do something stupid like:
git ls-files | grep Kconfig | xargs grep DEBUG

Thought it may be trivial to extend git grip while you are there anyway.
But obviously only if this is useful for more than just me.
