git-filter-branch: be more direct in an error message 

git-filter-branch requires the specification of a branch by one way or
another. If no branch appears to have been specified, we know the user
got the usage wrong but we don't know what they were trying to do ---
e.g. maybe they specified the ref to rewrite but in the wrong place.

In this case, just state that the branch specification is missing.
