In Zmacs, if the region is set, undo limits its actions to those fully
contained within the region.  If an action spread across the boundary of the
region, it failed.  This was a staggering win; I often find that I have made a
change to some code, and then edited a comment or docstring or something, and
realize that the code change I just made was silly.  With the current setup, I
have to either undo all of the text I have typed, or undo the code change from
memory.
