I am almost certain the output of cvs-fast-export is stable.  I
believe the output of cvsps-3.x was, too.  Not sure about 2.x.

I wrote the output stages for both cvsps-3.x and cvs-fast-export, and
went to some effort to verify that they write streams in the same
"most natural" way - marks sequential from :1, blobs always witten as
late as possible, fileops in the same sort order the git tools emit,
etc.

I have added writing a regression test test to verify the stability
property to the TODO list. I will have this nailed down before the
next point release, in a few days.
