It is because of the MIME emulating feature of Gnus that is
enabled by default.  It splits peculiar sections, e.g. uuencoded
data, non-MIME forwarded messages, etc., in the message body into
MIME parts.  Your problem is a typical case that this feature
works unwillingly, that is,  Gnus misidentifies the
"------------------------------%<------------------------------"
lines as the separators of the `insert-marks' part (See mm-uu.el).

The MIME emulating feature works only when displaying articles.
So, your messages will never be broken even if they look funny
to the recipients who use Gnus.  But there is no way to avoid it
other than to ask the recipients to disable this feature.  To do
that:

--8<---------------cut here---------------start------------->8---
(setq gnus-article-emulate-mime nil)
--8<---------------cut here---------------end--------------->8---

or

--8<---------------cut here---------------start------------->8---
(eval-after-load "mm-uu"
  '(add-to-list 'mm-uu-configure-list
                '(insert-marks . disabled)))
--8<---------------cut here---------------end--------------->8---
