Yes, that's definitely a good idea.  But comparison can still be
difficult in some cases.

For example, suppose version 5 is very old, version 10 removes the
ugly macros (so the only difference between versions 9 and 10 is
the cleanup), and version 15 is the current version.  If you need
to compare versions 5 and 15, or even 8 and 11, you're still going
to see a mixture of functional changes and cleanup changes.

If you can completely automate the process of fixing the macros,
in a way that works correctly even for older versions, you can
compare a converted copy of version 5 against version 15.

On the other hand, if versions of the code prior to version 9 are
uninteresting, it's probably not worth the effort; automating the
cleanup is likely to be worthwhile anyway, but don't worry about
automating 100% of it vs. 95%.
