Nah, you've got that the other way 'round. "patch" is not for creating
patches, it's for applying them. I've found, and some other people seem
to agree, that "patch" is more robust at applying patches than "git apply"
is. You might try this for a patch created with "git diff":

patch -p1 <patchfile

Be sure to cd to the top of the source tree first. Also, you can do

patch --dry -p1 <patchfile

if you just want to see whether it will complain without messing up
your tree.

(I gather from the messages it prints that the Patch Tester uses
"patch" not "git apply", so probably this patch would fail anyway.)
