Description:
------------
mod_fastcgi used to set PATH_INFO properly.

I use mod_proxy_fcgi+FPM through a UDS:

<LocationMatch "^/.+\.php(/.+)?$">
    ProxyPassMatch "unix:///run/php5-fpm-${SITE_USER}.sock|fcgi://localhost${DOCUMENT_ROOT}"
</LocationMatch>

This does not set PATH_INFO.

I have to use the unreliable 'proxy-fcgi-pathinfo' as a word-around.

SetEnvIf Request_URI "^" proxy-fcgi-pathinfo=first-dot

Please consider setting PATH_INFO.
Thank you.

BTW It is ok on PHP 7.0.15


Test script:
---------------
// Navigate to test.php/path-info

var_dump(isset($_SERVER['PATH_INFO']));
