chainlint.pl: don't require `&` background command to end with `&&`
The exit status of the `&` asynchronous operator which starts a command in the background is unconditionally zero, and the few places in the test scripts which launch commands asynchronously are not interested in the exit status of the `&` operator (though they often capture the background command's PID). As such, there is little value in complaining about broken &&-chain for a command launched in the background, and doing so would only make busy-work for test authors. Therefore, take this special case into account when checking for &&-chain breakage. Signed-off-by: Eric Sunshine <sunshine@sunshineco.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
