It is unclear (to me) what the impact of this patch is.  Does it fix a
problem which would justify including these patches in 2.6.26?

Also, your email client is performing space-stuffing.  That is easy
enough to repair at this end (s/^ / /) but please do sort that out for
next time.  http://mbligh.org/linuxdocs/Email/Clients/Thunderbird
should help.

Thanks.
