I don't think "git column" will run the pager by default, will it?
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.
