Re: tarsnap-keygen script usage

Oops, somehow I missed this when it first came in.

I don't think it's possible to specify a passphrase from a script unless
you fake a terminal -- given that a passphrase is supposed to be "something
you know" (and are sitting at a terminal typing in) rather than "something
you have" I'm not even sure why you want a script to provide the passphrase.
