POSIX actually specifies the behavior:

Ouch, right you are. I recall reading POSIX and coming to the opposite conclusion, that the behavior was not specified. Perhaps this was long ago and input files were required to be text files.

Anyway, since it's incompatible with other 'diff' implementations and with POSIX, and since there's not a particularly strong reason to differ, let's change to be compatible. I applied the attached patch to the savannah master and am taking the liberty of marking this as done; please give it a try.
