Hmm, I don't quite see where the current solution fails to do the right
$ cygrunsrv -I TESTsshd -p /usr/sbin/sshd -a -D -e "CYGWIN=tty binmode codepage:oem"
$ net start TESTsshd
The TESTsshd service is starting.
The TESTsshd service was started successfully.
$ ssh localhost

That would be a generic change to OpenSSH and /etc/sshd_config. I doubt
you'd get this approved by the upstream maintainers. I see your point,
but that's nothing which belongs into OpenSSH.
Suggestion: Start two sshds, one on port 22 and non-interactive for
external connections, one on port 2222 and interactive for local
connections. This solves the problem w/o changing OpenSSH sources.
