I've always wondered the extent to which svn-unapply works for people.
 It seems like sometime back, svn-unapply got behind svn-apply in
terms of functionality (perhaps around the time that support for Git
binary diffs was added to svn-apply).  This can happen because
svn-unapply is written separately from svn-apply.  They don't share
the same code path and so can get out of synch (this is a FIXME).
Maybe when Git users add functionality to svn-apply, they see less of
a need to make the corresponding change to svn-unapply since they
already have git-reset.  But I don't recall seeing any bug reports or
complaints about this from svn-unapply users.
