I believe it's IEEE Std 1003.2-1992 / POSIX.2. I found the initial
reference in the BSD/OS X man page[1], but google also found me other
references [2,3]. Also, elsewhere git uses "test -t 0", not "tty -s".

[1] http://developer.apple.com/DOCUMENTATION/Darwin/Reference/ManPages/man1/tty.1.html
    (The -s option is deprecated in favor of the ``test -t 0'' command.)
[2] http://docs.sun.com/app/docs/doc/816-5165/tty-1?a=view
    (Portable applications should use test -t.)
[3] http://opengroup.org/onlinepubs/007908799/xcu/tty.html
    (Portable applications should use test -t 0.)
