>Description:

I had a patch that removed some files, and I wanted to reverse-apply
it (with -R) to undo some version control lossage, but our patch
fails: it asks for a file to patch, and even if you specify the proper
path for the deleted file by hand it fails.

Using -p doesn't change the behavior.

Had to install gnu patch to do it.

>How-To-Repeat:

as above

>Fix:

dunno
