Fix oii(1df) so it works as a pipe
I realised I could make this work by recording a single byte in the temporary file with dd(1) and then emitting that and then the rest of the input with cat(1) if the file ended up with a byte in it. This lets me remove the CAVEATS section from the manual, as it no longer applies.

Run the given program passing in stdin but only if at least one byte of input
is actually received, rather like the -E switch to mail(1) behaves on
bsd-mailx. If no input is received, exit silently with an error status.
