You can easily test that using a * * COPY * * of
<URL:http://www.merlyn.demon.co.uk/js-quick.htm>. 'Press' Demo 6 times,
edit in your functions and their calls, press Eval. Repeat increasing
K_ and pressing Eval until you get reasonable times below the buttons.

In Firefox 3.0.19, WinXP sp3 P4/3GHz, K_ = 15000, I get 0,11,140,276
and similar - the FAQ is a little over twice as fast. Chrome 5.0,
0,10,34,59. Safari 5.0, 0,1,37,59. Opera 10.10, 0,0,140,422. But IE8,
0,0,344,297 - perhaps MS are comparatively good at RegExps.

The FAQ does need good, realistic examples of RegExps, though.
