I don't dispute the usefulness of this information.  However, I don't
think that rewriting old ChangeLogs is the correct way to do it.  The
basic idea behind a ChangeLog is that it is append only - warts,
spelling mistakes, and all.

I find it is the unchanging nature of a ChangeLog that makes it useful
when doing research.
