Summary svn-apply should be able to apply patches in reverse

Reported 2017-07-25 14:13:41 PDT
I would like to take advantage of svn-apply when rolling out changes. I propose adding a -R|--reverse option (API borrowed from the patch utility and git-apply) to the svn-apply script. The work here is minimal, since the underlying call to VCSUtils::generatePatchCommand already understands how to reverse patches.

Will this be different that the already existing svn-unapply?

I was unaware that svn-unapply existed; after taking a look I think it will serve my needs just fine.
