I noticed in another thread that somebody suggested git diff --no-prefix for creating patches.

Please don't do that any more. We've moved to standard git patches (git diff without the --no-prefix, meaning a patch -p1 patch).

Testbot support for -p0 patches (--no-prefix) will be removed around the end of May. See http://groups.drupal.org/node/140204

Some of you may have the --no-prefix stuff in your  .gitconfig. Please remove it from there as well.

In the issue queues, please start to insist on rerolls for -p0 formatted patches (if they have no a/ and b/ in front of the filenames.

Thanks for your cooperation.

-Randy
