"Check to make sure we successfully ignore trailing -- made by
'git format-patch'. This is bug #9597"
;; I made a test repo, put some files in it, made arbitrary changes
;; and invoked 'git format-patch' to get a patch out of it. The
;; patch and the before and after versions of the files appear here.
;; The test simply tries to apply the patch. The patch contains
;; trailing --, which confused diff-mode previously
