Ahh, I must have overlooked that; changes being only in _unmerged()
variant makes me feel much better, and it probably would make much

Again, true.  The mergy operations want to start from a clean slate
and they call _unmerged() variant primarily to learn that there were
unmerged entries in the index, only to abort the operation in that
case, so a change to _unmerged() variant should be safe for them.

I'll take another look at your patch later, but not before the 2.1
final, and by that time you may already have sent a reroll ;-)

Thanks.
