Not enough information is passed to hook_taxonomy when a term is updated

When hook_taxonomy is invoked when a term is updated (taxonomy_manager.admin.inc line 1766) it only passes data from the term_data table as argument.
When hook_taxonomy is invoked by the default taxonomy editor it passes a lot more information like the terms parents.
This results in problems in other modules like the taxonomy menu module. This expects the parents to be included (#742660: Taxonomy Manager integration)

I included a patch that adds the parents to the term info which solves the taxonomy menu issue.
But it might be better to extend the patch to make sure the same arguments are passed as by the default taxonomy editor.
