FYI:

One of the comments made at the kernel summit, was to have people trim
email when sending. It makes it a lot easier to reply then to scroll
down lots of lines of quoted text just to read something that only
references part of the email.

Don't be afraid to cut out quoted text. It does help (as I did in this
reply).

Right, and this should be in a separate patch, showing this error in the
change log.
