nixos tests: waitUntilTTYMatches: Log TTY contents on last try
If the test has not passed yet, on the last attempt it now outputs: machine: Last chance to match /logine: / on TTY2, which currently contains: machine: running command: fold -w$(stty -F /dev/tty2 size | awk '{print $2}') /dev/vcs2 machine: exit status 0 machine: <<< Welcome to NixOS 17.09.git.a804ef4 (x86_64) - tty2 >>> machine login: to help debug the problem. Notice the "logine" typo in my check.
