rev-branch-cache: fix message about overwritten data
If there is data at the end we ignore, we should not count them as overwritten.
This reveal that we something don't overwrite anything, this will be taken car
of in the next changeset.
# Tests to ensure that sha1dc.sha1 is exactly a drop-in for
# hashlib.sha1 for our needs.
