it does not fail on ""nginx -t""

{{{
# nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
# 

}}}


however, nginx refuses to start

{{{

I think, it would be nice to catch that error during ""nginx -t"" run"	enhancement	new	minor		other	1.13.x				"# uname -a
