Well, I can't regsub for "openacs-4" because we have other project root trees on the OpenACS CVS project. What I could do is have one call in the loginfo CVS file (the one that calls my script) for each project and pass a "-r foobar" (for what to regsub) to it.
As for the formatting and subject changes, I added them. Check out http://dev.openacs.org/forums/message-view?message_id=46496
