--python option does nothing without --tty

[Hood Chatham]

Without --tty, --python does nothing and there is no indication what is
going wrong. Either `-p` should imply --tty (see attached patch) or passing
one but not the other should print an error and exit with nonzero status.

Subject: [PATCH] Make -p/--python imply --tty

Without --tty, -p does nothing.
