Should I assume you're not using splitting in Gnus to split the IMAP
articles?  (is this even possible?)

That's pretty odd...are these lines with no group listed?  Is there a
\t after the msgid on those lines?  I'm not really seeing how that
could happen, unless the group name was somehow "^M" by accident...

Doing this in a backward-compatible way is going to be hard, I agree.
Since nnmail-cache-fetch-group does this:

      (when (search-backward id nil t)
	(beginning-of-line)
	(skip-chars-forward "^\n\r\t")
	(unless (eolp)
	  (forward-char 1)
	  (buffer-substring (point)
			    (progn (end-of-line) (point)))))

It's difficult to get it to work...the first thing that comes to mind
is to add a second line including more information which will never
get matched as a messageid:

examplemsgid29sdf13499@foo.bar.com	mail.lists.foo
***	((group . "mail.lists.foo") (server . (nnml "")))

ttyl,
