[RFC/PATCH] status: suggest 'git merge --abort' when appropriate

[Matthieu Moy]

We already suggest 'git rebase --abort' during a conflicted rebase.
Similarly, suggest 'git merge --abort' during conflict resolution on
'git merge'.

I think this is a good addition.

It wasn't immediately obvious without the context that the changed
code will trigger only during a merge, and not just any other case
where we have unmerged index entries.  show_merge_in_progress() is
only called when s.merge_in_progress is set, which in turn is set
only when MERGE_HEAD is there, so we are good here.

Will apply; thanks.
