rHG83a505b5cf85: revlog: don't include trailing nullrev in revlog.revs(stop=len(revlog))
Summary

This was an odd side effect of the nullid entry that's in the
index. The existing callers (mostly repair.py) seem to have handled it
fine. It doesn't seem intentional, and it's pretty surprising, so
let's remove that surprise.
