Commit dbc4aa0750717e08efe41a0267347d8046462c5c

Update showindex example I find the showindex example to be pretty useful on occasion, but there were are couple of output tweaks I wanted, plus I wanted the ability to specify a path to an actual index file instead of having to open the whole repository. This makes those changes and expands the example slightly.
