The patch looks fine, though Jens has to apply these. I'm just an
ostensibly glorified reviewer. :)

Indeed. And in addition to it being rejected by the reflector, it also
means your patch is mangled.

You're still sending non plain text email, so it's going to be rejected
by the mailing list filter. It also mangles your patch such that it
won't cleanly apply. You have to use plain text for this to work well.

I guess Keith already made that point too on the patch mangling, needs
more coffee. Also, it mangles the patch.
