This E-mail message, when viewed in Gnus, won't have proper line wrapping.
After some detective work, this appears to be because the paragraph breaks
in this message are marked by the <SP><EOL><EOL> character sequence.
If the paragraph breaks in this message are changed to <EOL><EOL>, then Gnus
will be able to properly line-wrap this message.
The examples in section 4.8 of RFC 2646 use <SP><EOL><EOL> as the paragraph
break character sequence. <EOL><EOL> also happens to be a valid paragraph
break sequence, according to the formal format=flowed syntax, but
<SP><EOL><EOL> is the formal character sequence that designates a paragraph
break:
[ ... ]
This could be encoded as follows (using '*' to indicate a soft line
break, that is, SP CRLF sequence, and '#' to indicate a hard line
break, that is, CRLF):
`Take some more tea,' the March Hare said to Alice, very*
earnestly.*
#
`I've had nothing yet,' Alice replied in an offended tone, `so*
I can't take more.'*
#
[ ... ]
So, essentially, the paragraph breaks in these examples are all "SP CR LF CR
LF".
