| 1855 | to clear those that weren't granted |

| 1857 | easiest way to do this is to add 1 |
| 1858 | to all the elements whose letters |
| 1859 | are given with the current policy. |
| 1860 | That way, all elements that are set |
| 1861 | by the current policy and were |
| 1862 | already set by earlier policies and |
| 1863 | through the original grant of rights |
| 1864 | will get the value 2 or higher. |
| 1865 | The last thing to do is to sweep |
| 1866 | through `letters' and keep the |
| 1867 | elements having the value 2 as set, |
| 1868 | and clear all the others. */ |
