Long line; I'd break after the &&.

Also, why are you not sending the output of config-test.go to
AS_MESSAGE_LOG_FD any more?  And why send stdout to /dev/null?  Either
you have to repeat the redirections, or you should group the two commands:

AS_IF([{$GOLANG run ... && $GOLANG help; } 2>&AS_MESSAGE_LOG_FD
