Yes and yes, I believe.

I think we're looking into getting the post-TAGNAME code, hopefully
something will come of it...

Unfortunately I don't know if they'll be tagging any more releases any
time soon.  =(

Ah, interesting.  Thank you -- another utility to go tinker with.

"Safe" and "reliable" are the key words here, of course.  :sigh:  I
think I'm inclined to agree, overall.

Even if we had to just delete any entries in the RCS-file that were
timestamped after the TAGNAME checkin and have a non-working RCS file,
this would probably be better than nothing.  It probably would still
take a reasonably robust script not to delete something it shouldn't,

For the same reason that they won't be tagging any more releases, asking
for help is a bit difficult.  We're working on this, too, but as with
all things, this takes time.

Most of the reason we need the history is around is to track feature
changes -- a lot of code-paths in this project end very abruptly and
unexpectedly, and several hours into investigating a feature we'll find
that it dead-ends and has been replaced by a completely different
system.  Some also induce crashes for unknown reasons, and the
changelogs would help in tracking these down too.
