Well, the patch generation step requires knowledge of what the
original source tree looked like.  Previously this was done by
extracting and patching second pristine copy and then doing a
recursive diff between the two trees.  This got broken at some point
and was a pain to fix.  It was easier (and better, imo) to integrate
git into the extract and patch steps than it was to fix the old
method.

Using git may offer other benefits too, if the maintainer has
need/desier of these capabilities and a willingness to learn more git.
For people that don't care about it, it'll hopefully be nothing more
than extra output during the build process.

Thanks
