Increment backend port also when commented

[henri-hulski]

This allows to grep the incremented port also for other backends then php-fpm with %backend_lsnr% in the web template.

This is an example how I use it in a wsgi app with gunicorn. It works out of the box with this patch applied.

Backend template:

;[%backend%]
;listen = 127.0.0.1:%backend_port%

;user = %user%
;group = %user%

;listen.owner = %user%
;listen.group = www-data

;pm = ondemand
;pm.max_children = 4
;pm.max_requests = 4000
;pm.process_idle_timeout = 10s
;pm.status_path = /status

;env[HOSTNAME] = $HOSTNAME
;env[PATH] = /usr/local/bin:/usr/bin:/bin
;env[TMP] = /home/%user%/tmp
;env[TMPDIR] = /home/%user%/tmp
;env[TEMP] = /home/%user%/tmp

Nginx web template (*.stpl):

server {
    listen      %ip%:%web_ssl_port% ssl http2;
    server_name %domain_idn% %alias_idn%;
    access_log  /var/log/nginx/domains/%domain%.log combined;
    access_log  /var/log/nginx/domains/%domain%.bytes bytes;
    error_log   /var/log/nginx/domains/%domain%.error.log error;

    ssl_certificate      %ssl_pem%;
    ssl_certificate_key  %ssl_key%;

    client_max_body_size 10M;
    keepalive_timeout    15;

    location / {
        proxy_pass          http://%backend_lsnr%/;
        proxy_redirect      off;
        proxy_set_header    Host                    $host;
        proxy_set_header    X-Real-IP               $remote_addr;
        proxy_set_header    X-Forwarded-For         $proxy_add_x_forwarded_for;
        proxy_set_header    X-Forwarded-Protocol    $scheme;

        # Define the maximum file size on file uploads
        client_max_body_size 5M;
    }

    location ~ /\.git/  {return 404;}

    error_page  403 /error/404.html;
    error_page  404 /error/404.html;
    error_page  500 502 503 504 /error/50x.html;

    location /error/ {
        alias   %home%/%user%/web/%domain%/document_errors/;
    }

    location ~* "/\.(htaccess|htpasswd)$" {
        deny    all;
        return  404;
    }

    location /vstats/ {
        alias   %home%/%user%/web/%domain%/stats/;
        include %home%/%user%/conf/web/%domain%.auth*;
    }

    include     /etc/nginx/conf.d/phpmyadmin.inc*;
    include     /etc/nginx/conf.d/phppgadmin.inc*;
    include     /etc/nginx/conf.d/webmail.inc*;

    include     %home%/%user%/conf/web/snginx.%domain%.conf*;
}
