Patch by Kees and José Matos. For discussion, please see this [1] ML thread. José additionally notes [2] the following: I took the change and I changed some minor annoyances: * test comparison with None; * fixed a region where the indentation was different from all the others (2 spaces instead of 4); * replaced xrange with range.
