Comment:

 Though I posted to [http://wppolyglots.wordpress.com/2012/06/26/all-
 translators-did-anyone-have-a-locale/ the P2], I was able to sufficiently
 script this.

 These locales had a locale.php file in their latest 3.3.x build but not in
 their 3.4 final build: sv_SE
 pl_PL
 ar
 id_ID
 nb_NO
 fi
 en_CA
 nn_NO
 eo
 ckb
 pt_BR.

 zh_CN, he_IL, and ru_RU still do have locale.php files.

 All of these locales are either $wp_default_secret_key or $text_direction,
 so they are harmless. pl_PL also adds a date declension filter, but again,
 harmless as-is and won't break core. So, moving to 3.5.

 This is not as easy as just adding files to `$_old_files`, because we have
 to detect a custom language directory. Here's a patch that is one way to
 implment this.
