I don't think that will work, because it'll output the changes as
individual patches in reverse order (newest first) which will be
no good when trying to feed it into patch or git apply.

I think what you instead want is:

  git diff origin/master...FETCH_HEAD > sabre-lite.patch

which will be the changes that are in FETCH_HEAD that aren't in
origin/master as a single patch.

Thanks - one of the issues is that not everyone knows the details of
distribution package build systems (each distro seems to have their
own unique way of building and packaging stuff.)
