diffutils seem to be going backwards and forwards on this one, eg

http://lists.gnu.org/archive/html/bug-diffutils/2012-01/msg00009.html

Paul can probably tell us the current thinking...

Anyway, what about Solaris's diff, which has neither -L nor --label?

Why not test for this option, which Emacs presumably uses only for
cosmetic effect, before using it?
