The problem is having to manually insert the version number into half a
dozen different files, in half a dozen different formats, while
preparing an update release.  (And multiply that by several back
branches, with several slightly different sets of changes to make.)
This is not only tedious but quite error-prone --- if you check the CVS
logs for the affected files you'll note we have missed changes more than
once.  I don't think we've yet wrapped a mis-labeled tarball, but it's
going to happen sooner or later if we keep doing this manually.

I suspect you are wondering why we don't use the makefile infrastructure
to fix the numbers instead.  I think the reason is that most of the
files in question are for Windows and we can't assume very much about
the available tools for fixing them at build time.  In any case, I'd
be hesitant to back-patch such a fix.  Doing it this way means that the
script only has to work on our own machines, not in any weird build
environment someone might have, so it seems a lot safer to drop into
the back branches.
