Setting process-connection-type to nil on Carbon Emacs is broken

[Andrew Nesbit]

Symptoms:

When process-connection-type is set to nil, Tramp does not work with
the ssh connection method.  Nor does ssh work in a *shell* buffer,
outputting a "Pseudo-terminal will not be allocated because stdin is
not a terminal." error message.

However, using "ssh -t -t" does work.

It seems that this is a bug in Emacs itself, rather than Tramp or ssh,
as ssh works correctly from the terminal and Tramp works with the
sshx connection method (which specifies the "-t -t" options).
