su command in *shell* buffer does not work.
su does not ask for the password and exits with "su: Sorry".
The value of process-connection-type variable is t.
There are no .zshenv, .zprofile, .zshrc, .zlogin, .zlogout, .cshrc and .login.

1. emacs -Q
2. M-x shell

/* *shell* buffer (24.4.90) */
Warning: no access to tty; thus no job control in this shell...

Akira Shirai, thanks for the info about grantpt and its internal setuid program; 
that made the problem obvious.  I installed the attached patch into the Emacs 
master sources and am (perhaps optimistically) marking this bug as done.
