ssh opens the controlling terminal (/dev/tty) directly to read the
password. I think there is no way to tell ssh to read the password
from stdin. If you want to use ssh locally, you need to create a
pseudo-terminal. Depending on your operating system, this may be an
arbitrarily complex procedure, or not possible at all. With some luck
(e.g. on Linux), you may have the functions posix.openpty and
posix.forkpty to do that.
