That's unfortunate.

In my experience, it seems to be that typically the ordering *is*
preserved.  Indeed, we use this assumption to help the heuristics that
choose symbol parents in cvs2svn; e.g., the decision of whether branch was applied to branch 1.5.2 or (or even,
which can happen if branch was created, deleted, then
recreated).  Resolving this ambiguity is a big headache for cvs2svn and
the apparent reverse-chronological ordering of symbols was one of the
straws that I grasped at.

Larry, do you know of specific situations where the symbol ordering is
not preserved, or are you just reluctant to guarantee that it won't
happen in the future?

I would also like to encourage CVS developers *not* to disturb the
ordering gratuitously :-)
