Is there some place today that we explain the many rules Git uses to determine the operations in progress? I once had a patch to do this in code, but I think I let it die in committee. It was something like:

     $ git status --show-progress-state
     cherry-pick, conflicts, untracked

It would be helpful first to have an API for this, of course, though I think that's where I got mired before.

I'm willing to take it on again, if there's not already some alternative.
