I *think* you're actually agreeing with me.  *Hiding* the diffs that
include munching of keywords is not what we want.  We want the
conversion to *not* munge "keyword-like" things (No, $OpenBSD$ is *not*
a keyword in the PostgreSQL CVS repository.  But $PostgreSQL$ *is*.

So we want the conversion to be identical to:    cvs export -kk -r $tag

That will have *keywords* be unexpanded; namely these specific
ones:AuthorDateHeaderIdLockerLogNameRCSfileRevisionSourceStatePostgreSQL
but *not* "keyword-like" entries, like:$ NetBSD ... Exp $$ FreeBSD ... Exp $$ OpenBSD ... Exp $$ KAME ... Exp $
which are *not* CVS keywords in the PostgreSQL repository.  

i.e. Just like I said, "identical to cvs checkout/export -kk.


Now, and intersting question, do you want the "perfect" conversion to
contain *other* keyword un-expansion possiblities that would have happened
on any commits on Nov 29/30 2003 when CVSROOT/options contained:+tagexpand=iPostgreSQL
If you had checked out something on that day, even with a -kk, $Log$
would have been expanded, because for that day, $Log$ was *not* an
eligable keyword on the PostgreSQL CVS repository.

Whooee... Fun with CVS history....
