function _menu_build_local_tasks

Find all the items in the current local task tree.

Since this is only for display, we only need title, path, and children for each item.

At the close of this function, $_menu['local tasks'] is populated with the menu items in the local task tree.

Return value

TRUE if the local task tree is forked. It does not need to be displayed otherwise.
