rev-list: don't show usage when we see empty ref patterns
If the user gives us no starting point for a traversal, we want to complain with our normal usage message. But if they tried to do so with "--all" or "--glob", but that happened not to match any refs, the usage message isn't helpful. We should just give them the empty output they asked for instead.
