Looking at the code, it just returns the first two "words" after
"diff -OPTION":
;; this assumes that there are no spaces in filenames
(when (re-search-backward
"^diff \\(-\\S-+ +\\)*\\(\\S-+\\)\\( +\\(\\S-+\\)\\)?"
nil t)
(list (if old (match-string 2) (match-string 4))
(if old (match-string 4) (match-string 2)))))))))
I guess we could filter out "-L +\\S-+" before matching? But I don't
think I've ever seen "-L" in the wild, so I don't know whether it's
worth doing.
