Unfortunately, this will never solve the problem entirely. Global
autostash mode probably will, more chances if stash will save/restore
exact state of everything when applied to the original base.

It is not entirely separate. If --merge goes away, there will be no
"squat on -m" anymore.

Personally, I'd just turn on global autostash mode if it were available,
and forget about both --merge and --autostash, for the better.
