    Normally a caller that invokes setup_revisions() has to
    check rev.pending to see if anything was actually queued for
    the traversal. But they can't tell the difference between
    two cases:
    
      1. The user gave us no tip from which to start a
         traversal.
    
      2. The user tried to give us tips via --glob, --all, etc,
         but their patterns ended up being empty.
    
    Let's set a flag in the rev_info struct that callers can use
    to tell the difference.  We can set this from the
    init_all_refs_cb() function.  That's a little funny because
    it's not exactly about initializing the "cb" struct itself.
    But that function is the common setup place for doing
    pattern traversals that is used by --glob, --all, etc.
