Well, that's for the --non-interactive flag. I was thinking of adding that as a
benefit of allowing certain options even if the command doesn't do anything for
this option right now, but I noticed 'svn merge' 1.4.x already takes the
--non-interactive option. So the 'infrastructure' was already there,
svnmerge.py just didn't use it yet.
