Subject: filter-branch: assume HEAD if no revision supplied

filter-branch previously took the first non-option argument as the name for
a new branch. Since dfd05e38, it now takes a revision or a revision range
and modifies the current branch. Update to operate on HEAD by default to
conform with standard git interface practice.
