Create a job to regenerate display and sort names

After changing the display settings (/civicrm/admin/setting/preferences/display) for sort_name or display_name there should be a way to regenerate the sort_names and display_names currently in the database to the newly configured format.

In http://civicrm.stackexchange.com/questions/872/is-there-a-way-to-regenerate-the-display-and-sort-names creating a job was suggested for this. It would be great if this would just be executed just like the update greetings and adresses.
