IIRC it is legal, but not good practice.

In the current development version, we get:

--8<---------------cut here---------------start------------->8---
ELISP> (and (require 'gnus) (require 'rfc2047) gnus-version)
"No Gnus v0.3"
ELISP> (with-temp-buffer
	 (insert "Subject: Re: Forsvarsminister svært bevæbnet i Afghanistan")
	 (rfc2047-encode-region (point-min) (point-max))
	 (buffer-string))
"Subject: Re: Forsvarsminister =?iso-8859-1?Q?sv=E6rt_bev=E6bnet?= i\n Afghanistan"
--8<---------------cut here---------------end--------------->8---

This is good.  But with the stable version (5.10.7 or from Emacs CVS),
we get folding directly after "Re: ":

--8<---------------cut here---------------start------------->8---

"Gnus v5.11"

	 (insert "Subject: Re: Forsvarsminister svært bevæbnet i Afghanistan")
	 (rfc2047-encode-region (point-min) (point-max))
	 (buffer-string))
"Subject: Re:\n =?iso-8859-1?q?Forsvarsminister_sv=E6rt_bev=E6bnet_i_Afghanistan?="
--8<---------------cut here---------------end--------------->8---

We already considered to sync `rfc2047.el' in the stable branch with
the trunk version.  I hope Katsumi Yamaoka will find to do it, see
<http://thread.gmane.org/v93bvpyk3d.fsf%40marauder.physik.uni-ulm.de>.

Bye, Reiner.

Hi,

Please merge the changes I made in the v5-10 branch today into
the Emacs trunk.  However, please don't bring back them into the
Gnus trunk because they are for only Gnus v5.11.  The files which
I've changed in the v5-10 branch correspond to the following
ChangeLog entries:

Sorry I kept you waiting.  emacs-w3m 1.4.4 has been released.
I sync'd rfc2047.el with the trunk as a starter.  It has been
tested not only with recent Emacsen but also with Emacs 20.7 and
XEmacs 21.1.14.  I will take a vacation next week and will start
the work on nnrss.el from the week after next (i.e., April 4).

Regards,
