The patch itself looks ok, but unfortunately, you have a few
formal mistakes in the submission. Most importantly, the long
lines got wrapped by your mail client, so it won't apply.

About the start of the mail, please put the 'We would like to...'
part and everything else that is not supposed to show up in
the changelog _below_ the introduction, separated from the
changelog with a single line containing the string '---'.

The Subject: line should not be in the mail body, it's only
used if you want to use the 'quilt mail' tool, which will
move it to the real subject of the mail.

The From: line can only have one name in it. If you want to
give credit to multiple people, that should be in the
changelog text.

Please resend.
