The -n is a speed up and simplification, as when there is no input stdin only output, ssh does not need to fork off a child or thread to watch stdin. Some commands get very confusing without it, like:
Both 'ssh2' and 'pg' will be reading /dev/tty, so 'pg' will seem unresponsive half the time, because 'ssh2' does not know 'ls' does not read stdin.

LEARN ABOUT SUSE
showconsole
SHOWCONSOLE(8) The SuSE boot concept SHOWCONSOLE(8)NAME
Showconsole - determines the underlying tty of stdin
Setconsole - sets the underlying tty of /dev/console
SYNOPSIS
showconsole [-n]
setconsole /dev/tty<xy> < /dev/console
DESCRIPTION
showconsole determines the underlying character device of the current stdin. This can be used on /dev/console as current character device
to get the real character device back.
setconsole sets the underlying tty of the system console /dev/console. This requires that the standard input is identical with /dev/con-
sole and exactly one argument, a valid character device is given.
OPTIONS -n Return the major and minor device numbers instead of the device file name. This can be used to asked the kernel for the major and
minor device numbers of a not existing device file in /dev.
BUGS
showconsole needs a mounted /proc file system and tries to set the controlling tty to stdin if no controlling tty is found. After reading
/proc the status of the controlling tty is restored to avoid problems with getty processes.
FILES
/proc/<pid of showconsole>/stat
the stat file of the showconsole process.
/dev/console
the system console.
