This patch is still corrupt.

Before sending it to us, you should send it to yourself, and check that
it can be applied with "git am" or "patch -p1".

Also, when sending a new version of a patch, please include a changelog
that explains what is different about the new version.  If it's just a
resent version of the old patch, you can write that.

Thanks,

- Chris.
