Hi!

I'd like to have git-format-patch diffs to be properly identified when I'm
using Gnus to read mailing-lists.  It mostly works fine, *if* the
(inlined) patches include a signature at the end ('--').  If the signature
is missing then the patch isn't identified as such.

Since all the other diff formats in mm-uu-type-alist don't have the
'end-point' I thought it would be fine to also remove it from the
'git-format-patch'.

The issue I'm trying to fix can be easily seen in Gnus by comparing two
emails with the following message-ids from the emacs-devel@gnu.org
mailing-list:

  87v81dmhxi.fsf@orpheu.olymp
  20240702155100.2150717-1-brennan@umanwizard.com

(These emails can be accessed by entering the Gnus group, hitting 'j'
(gnus-summary-goto-article) and yanking the above message-ids.)
