Hmm...I'm using Thunderbird 3 beta4, and it appears that when sending
via the "preformat" mechanism it actually does perform space-stuffing.
This is visible as an extra leading space when looking at the raw source
of the sent (or received) email via ctrl-U.

However, if one turns off format=flowed, but leaves wrap set to 72, then
the html preformat works without having to set the wrap to 0.

Thanks,

Chris
