I'm inclined to say we should just let the icon work like it used
to, stage the whole working copy.  That's exactly what it does on
a non-merge, and thus is what it should do on a merge.

As a safety feature we can scan the working copy for merge marks if
we are currently in a merge and prompt the user for confirmation
if it looks like they are merging an unmerged working copy.

Run git-merge-file after extracting the stages to temporary files.
You can also jam the stages back into the index with update-index
--index-info.
