All of these patches have annoying whitespace breakage. It appears your MUA is adding an extra SP at the beginning of every single line that begins with a SP, or something.

Care to redo the series?

Hmph. My ISP's smtp-server was down last night so I tried using sendmail, but neither vger nor mx-all.pobox.com liked my (dyn)dns. So I ended up using Opera against gmail. Next time I'll just wait for my ISP to come back from lunch ;-)

Sure.
