-f - is a standard convention for a lot of stuff already in the source tree.

Yes, /dev/stdin or /dev/fd could be used (if you've bothered to mount fdesc),
but in general is never going to be something folks will see as examples or
would think of. So, adding it in as an option as well just rounds things out.
