And presumably \x00 ?

My index code is as strict as container 1 formats. I'd like to do a scan
of all the repositories on the supermirror before we loosen this because
I strongly suspect we don't have space containing revids out there, and
don't see a good reason to have them in the core- it limits our
fast-parsing options more than a little.
