What a strange thing.  `kill-region' is not related to word commands
in no way.  Why not kill a sentence?  Why not kill a line?  Why just word?
All existing commands handle an active region.  But there is no commands
that do in the opposite direction where a general command handles
one random specific case.  This is because the region is a more
general concept.
