 The `settings` file has variable named `Unregisterised` which on most
 arches is sed to `NO`.

 I propose that the variable be renamed to `Registered` (dropping the
 "ised" part as well) so that:

 {{{
       Old                           New
 ("Unregisterised", "NO")   ->    ("Registered", "YES")
 ("Unregisterised", "YES")  ->    ("Registered", "NO")
 }}}

 Unless someone can come up with a good reason why it should stay as it is,
 I will submit a patch for this to phabricator.
