Sorry, but you need to be much more clear why this could be a good
thing.

Everywhere in git a range A..B means "reachable from B but exclude
everything that is reachable from A", and with that knowledge it is
natural to expect that master..master should yield an empty set. If you
need to change it for some reason, we need to know why, and if you are
doing it for a narrow special case, we need to know why that case is so
special.
