function translationInfo($table,$uid,$sys_language_uid=0, $row = NULL) {

Please be consistent with the spacing (I prefer space after comma, no
spaces around =, but check CGL). The doc comment for the new argument is

IIRC CGL require booleans in lower case.

Other than that the patch looks ok, so +1 by reading if you solve the
