Thanks. Still this patch does not apply. How did you generate and send
it? It's somehow mangled. I suggest to use git send-email.

And another issue: The subject of this original mail still has "Re: " in
it. Please don't reply in some mail client but either use git send-email
or write a completely new message. Some mail clients tend to clutter
the whitespace etc.

Thanks,
Stefan
