New filter `wp_page_path_sql`

[sebastian.pisula]

Make plugin for translations I found next missing filter. WordPress use get_page_by_path in WP->parse_request();

In post meta I save info about language version.

Example:
"Contact" in German and Polish is "Kontakt" so slug will be 'kontakt'. Function get_page_by_path fiund by slug in all languages. But in filter wp_page_path_sql I can add LEFT JOIN and set current language.

I know that exists parse_query action and I can change query via this action but before in wp_page_path_sql will be generate unnecessary sql.

This sql filter will be usefull very much.
