[wplug] nitpicky thunderbird question

[Patrick Wagstrom]

Alrightey Thunderbird users, here's my question for you.  I've got 
Thunderbird set up to send all my email as plain text.  When I edit the 
text in my mail program it wraps at about 80 characters, but when I 
receive messages sent by me they don't wrap.  Many mail clients don't 
handle this properly and force the user to scroll to the end of the line 
to read it.  Like this line here.

So, anyone know how to get Thunderbird to send in plain text and put 
line breaks at around 80 characters on each line?
