You'd need "git -p" here. That said, I'm still puzzled why it would return zero output. Strace shows that the read from stdin is getting no input. I suspect this may have to do with how we redirect stdin in test-terminal.perl. See 18d8c26930 (test_terminal: redirect child process' stdin to a pty, 2015-08-04), which claims there's some raciness with closing the descriptor. -Peff
