This is the case where a patch is in the text/plain body.
Because of the value of `gnus-article-treat-types', gnus-treat-*
is performed on it.

One is to improve `message-cite-prefix-regexp' so that it doesn't
match a single `+' or `-' in the beginning of lines.  (Maybe I've
never seen replies in which a single `+' or `-' is used for the
citation.)  For example:

--8<---------------cut here---------------start------------->8---
(setq message-cite-prefix-regexp
      "[\t ]*\\(?:[[:word:]]+[-._[:word:]]*\\(?:[\t ]*[]+>|}]+\\)+\
\\|\\(?:[]>|}][\t ]+\\|[]+>|}][]+>|}]+[\t ]*\\)\\(?:[]+>|}]+[\t ]*\\)*\\)")
--8<---------------cut here---------------end--------------->8---

Another is to pull "text/x-patch" from `gnus-article-treat-types'
and to make mm-uu.el dissect a patch in the text/plain body as a
text/x-patch part.  I have currently no concrete idea to do that,
though.
