I'm assuming that based on the issue queue and lack of recent commits that this module is no longer actively maintained, and that the likelyhood of this patch making it in is extremely low, but I'm putting this out there for anyone who will gain some benefit from it.
The patch adds the ability to filter a User View based on the Administer Users by Role edit permissions, which in combination with the User management View defined in the latest 1.10 Beta of the Views Bulk Operations module (or a another User View) makes for a better user experience by only showing editable users instead of showing all users and simply erring when the user tries to edit a user they don't have permission to edit.
Hope someone finds this useful as it wasn't the easiest thing in the world to get working.
