Fix a bug in cygtermd, spotted by Casey Zacek, in which we
unconditionally set the telnet state to SEENCR regardless of whether
we have actually seen a CR, and as a result sending a NUL through
PuTTY (via Ctrl-Space or whatever) does not work. Must have arisen
through some kind of really weird cut-and-paste error!
