Samuel John c1bab919b9 python: Use patch (from upstream) instead of inreplace
This patch is different than my earlier ad-hoc solution, but it took
some time until upstream devs came up with the proper fix. However, we
can't directly link to the patch (from the mercurial web repo), as it
also changes the NEWS text and the patch fails to apply. Further, the
mercurial repo is only http (no "s").
