It does work better for binary files, though there's little benefit in storing
binary cryptographic keys as opposed to ASCII ones. Unfortunately for the
cfbot, "git apply" forces the equivalent of "patch -F0", so it rejects patches
needlessly. If you do change the cfbot, I recommend having it start with "git
apply -3" (able to succeed when plain "git apply" fails), then fallback to
"patch" when "git apply -3" fails.
