This is an unfortunate left-over.  The syntax described in the 
documentation should be right.

Hmm.  I don't have time to look into this now, but the syntax is this:

	git filter-branch [<options>] [--] [<rev-options>]

Those refs that you give in the <rev-options> are rewritten.  AFAIR the 
old values of the refs (if different) are written to refs/original/*.

To rewrite refs.

No, this will not happen.  Filter-branch is meant to clean up branches, so 
it will rewrite the commits.  However, you might be able to hack something 
in a parent filter.
