Programmatically delete nav menu item

[virgodesign]

It seems that does not exist a direct fuction for deleting a nav menu item programmatically, using php.
Something such as wp_delete_nav_menu_item, a function that would delete a nav menu item from the database, correctly and definitely.

There is a question partially answered here:

​http://wordpress.stackexchange.com/questions/60872/how-do-i-delete-not-exclude-a-menu-item-from-navigation-bar

Using wp_delete_post seems to be a workaround, as it will not update correctly all the databases entries that are involved.

Maybe a working solution could be:

1. Delete the nav menu item from wp_posts using wp_delete_post (the 8 postmeta options involved will be also deleted).
2. Delete the nav menu item from wp_term_relationships.
3. Update the counter of the nav menu in wp_term_taxonomy.

I'm not sure if I'm missing something else, but I think this could be a staritng point. Any suggestions or comments would be very appreciated.
