Actually the best way to generate random chars like the above
is to avoid -p entirely. So I've made -t consistent and
output /tmp/... in the above case.

Also I matched the -q option up with the documentation.
The documented functionality made sense, which was to
suppress only I/O errors, but the existing code suppressed
almost all errors, including most usage errors.
So I fixed that up in a second patch.

Both updated patches are attached,
and already pushed.

thanks,
Pádraig.
