function _menu_position_form_menu_edit_item_alter in Menu Position 7

Same name and namespace in other branches

1. 6 menu_position.admin.inc \_menu_position_form_menu_edit_item_alter()
2. 7.2 menu_position.admin.inc \_menu_position_form_menu_edit_item_alter()

Implements hook_form_menu_edit_item_alter().

This handles the edge case of another module accidentally exposing (or of a user hacking the URL to) the standard "menu link edit" form for a menu position rule's hidden menu link. We alter the form so that it is not posible for the link to be edited.
