I think the important point - and why I asked for a bugreport after
talking about it on irc - is that sprompt.c on windows uses
CONIN$/CONOUT$ for io. Ignoring stdin/stdout except when the OSTYPE is
set to msys. Given that CONIN$/OUT seem to refer to the shell that
started a processtree from a shell that doesn't seem to be optimal.

That said, I am not a big fan of relying on sending the passwort to
stdin...
