That makes "repo" field optional and I'm very much against falling
back to the_repository. revisions.c in the end does not have any
the_repository reference, and it's actually undefined for most files.
This makes accidentally adding the_repository back much more
difficult.
Yes the --no-index stuff will have to be taken care of at some point,
but I think for now we could just put "struct repository *" in place
first to see what it looks like, then go from there.
