Okay, I've changed that.

I thought it was nice to preserve the user's preference between page loads. But, it also may make sense to show the index for a 
newly fetched page so the hierarchical location is readily apparent.

If you don't like it and want to disable the feature, simply comment out line 48:
set_indexbar_from_session();

Let's see if the G-overlord allows this attachment.
