This looks like a job for your para-walk topic. For this git-commit
case we just need a

  git-ls --no-workdir --error-unmatch HEAD -- <pattern>...

to replace git-ls-files. To my untrained eyes it looks like this is
mostly there (AFAICS it doesn't do pattern matching and the
--error-unmatch thingy).
