Please explain more.  The above advice was based on a guess, and it
turns out I guessed wrongly.  What exactly do you want to test for?

Was the change in files.el made before the 23.2 release branch was
cut, or after it?  If the latter, was it made to both the trunk and
the branch?

Perhaps the various predicates for comparing versions could help you
(version<, version<=, etc.).
