I usually go by git-status, but I am not the watched normal user,
hopefully. Maybe we want to run git-status after a failed merge
for the user, too, though?

I would think we would want to highlight the type of conflict as well,
e.g.

  <RED> CONFLICT> <RESET> \
  <BOLD;RED> (rename/rename): <RESET> \
  Rename a -> b in branch foo \
  rename a ->c in bar

but then again, this patch is better than not doing any colors.

I wonder if we want to have certain colors associated with certain
types of merge conflicts, e.g. anything involving a rename would
be yellow, any conflict with deletion to be dark red, regular merge
conflicts blue (and at the same time we could introduce coloring
of conflict markers to also be blue)
(I am just making up colors, not seriously suggesting them)

I like the idea!

Thanks,
