I suppose revert in the case of pending merge (from commit --local) is
not what user actually want, right?

If user want to restore local commits to the state before update then we
need to `pull . -r revid:pending-merge-tip --overwrite` instead.

Gary, I've tried to reproduce your steps. Uncommitted changes in file 2 is properly backed up as file.ext.~1~. So there is no real data loss.

I'm sure this bug occurs because of the problem with select all checkbox: it should takes 3rd state when some files unchecked in file view. See bug https://bugs.launchpad.net/qbzr/+bug/524483
