Have you read the Info documentation ? Particularly, see
`(diff)Shortcomings' and from the menu there `(diff)Special Files'.
In fact, diff (the program) doesn't consider it an error, since it
gives a zero exit status.

The GNU people actually seem to agree with me that this is a bug
(shortcoming, whatever) in their program.
In fact, the `Special Files' node contains some suggestions for future
improvement that I agree would be very usefl.
If you prefer please reopen the bug and mark it forwarded.
