Yeah, I'm not too concerned with the fact that this can't be inlined, 
though I probably should just remove that from the lib (looks like that 
was a recent addition).

I'm more concerned with the larger issue that it's not doing what it 
says it should be doing.

Grrrr... I want formatting too :(. Vladimir, we need an X-DFormat = 
markdown header or something I can use in Thunderbird.
