I'm a bit confused by this, the proposed test uses this hook script

	write_script .git/hooks/pre-commit <<-EOF
	test -t 1 && echo "stdout is a TTY" >out
	test -t 2 && echo "stderr is a TTY" >>out
	EOF

if either of stderr or stdout is redirected then the corresponding "test 
-t" should fail and so we will detect that it is not a tty.

Best Wishes

Phillip
