Description

Hello.

Prior version 1.18 next config validation was worked:

nginx -t -c /dev/stdin <<< "events {worker_connections 1;} http { include /some/config.conf; }"

That had been used for ansible config validation, please refer to [this atackoverflow answer](https://serverfault.com/questions/674092/validate-nginx-conf-during-ansible-deploy/811520#811520).

For now that behaves very strange:

$ sudo nginx -T -c /dev/stdin <<< "events { worker_connections 2; } http { include /home/pasha/temp/nginx.validate/some.conf; }"
nginx: the configuration file /dev/stdin syntax is ok
nginx: [emerg] no "events" section in configuration
nginx: configuration file /dev/stdin test failed

As you see, events block is here!

$ cat /dev/stdin <<< "events { worker_connections 2; } http { include /home/pasha/temp/nginx.validate/some.conf; }"
events { worker_connections 2; } http { include /home/pasha/temp/nginx.validate/some.conf; }

Meantime, that worked with regular file:

$ bash -c 'echo "events { worker_connections 2; } http { include /home/pasha/temp/nginx.validate/some.conf; }" > /tmp/nginx.conf; sudo nginx -t -c /tmp/nginx.conf; rm -f /tmp/nginx.conf'
nginx: the configuration file /tmp/nginx.conf syntax is ok
nginx: configuration file /tmp/nginx.conf test is successful

This never worked, including in nginx prior to 1.18.x, but might appear to work if your shell used to provide here-documents in temporary files. See #2381 for details.
