Thank you for the patch, but it appears your mail client has mangled the patch
so it does not apply cleanly. As a general rule, you should be able to save
the email and apply it directly to the tree; if not, you are doing something
wrong.

Have you read the notes in the Documentation/SubmittingPatches file, yet? If
not, I suggest taking a look, there is a lot of good information there on
submitting patches to the mailing list.
