Re: [PATCHv3 1/3] merge: Add '--continue' option as a synonym for 'git commit'

So not too bad (and you could probably refactor it to avoid some of the

  git merge --continue --verbose --quiet

I dunno. Maybe I am leading you down a rabbit hole, and we should just
live with silently ignoring useless options.

I think you need to handle this in parse-options API if you really
wanted to do this correctly.  

[ref] may serve as a
reasonable outline for building one.
