[PATCH] split group names with "\\n" in them

[Didier Verna <verna@inf.enst.fr>]

        I've found the problem that I reported earlier (where groups
containing \\n in their names generated a bogus mail:n group). The reason is
that nnmail-article-group passes non expanded group names to the functions
that update the active file. The following patch fixes it.


1999-04-12  Didier Verna  <verna@inf.enst.fr>

	* nnmail.el (nnmail-article-group): in case of a group name
	containing "\\n" constructs, be sure to pass the expanded value to 
	nn*-save-mail.
