Use "test -t 0" instead of deprecated "tty -s" to detect when stdin is a terminal.
Who deprecated it? Other changes looked sensible, though.

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".

(The -s option is deprecated in favor of the ``test -t 0'' command.)

(Portable applications should use test -t.)
