The RFC is clear on this, see quote below, the 
above would be incorrect.  However, this should be 
fixed in CVS, both for Gnus 5.10 and No Gnus, so an 
upgrade should solve the problem.

   An interpreting agent SHOULD allow for three exceptions to the rule
   that paragraphs end with a fixed line.  These exceptions are
   improperly constructed messages: a flowed line SHOULD be considered
   to end the paragraph if it is followed by a line of a different quote
   depth (see 4.5) or by a signature separator (see 4.3); the end of the
   body also ends the paragraph.

I have made this message an example of this problem, so that people
can test whether code works or not.  I had to fix a bug in No Gnus to
make unquoted lines flow too.
