It would be nice. 

Maybe other users have a different experience, but for me 99% of the
time I would like undo info after a revert is when revert was invoked
by VC/pcl-cvs after a commit.
So from this users point of view if VC/pcl-cvs were not to revert the
buffer, saving undo after revert would not be missed much.
