Right, this is possible though it would have to be checked whether it is 
supported, so that statement should be weakened a bit -- to allow 
deleting non-free files with a patch, but noting that you'll have to set 
the right options to avoid including the deleted file in the patch.

I would recommend a (delete-file-recursively ".") over a patch here 
though, to avoid having to remember the --irreversible-delete option and 
in case there is not a git repo.
