Answering my own question to an issue I kept running into with Backbone.js...
In my Backbone applications, I want users to be able to navigate directly to a an interior "page" without having to type a hash (#) in the URL. Out of the box, Backbone Boilerplate doesn't seem to support this even though it does support pushState.
Users already could reach any location as long as they start at the homepage, obviously. Or they could skip straight to an interior page, but only if there was a hash (#) directly after the domain or immediately after an initial slash.
I found a solution to this problem that seems to be working. I'm posting it here for others with the same problem, to see if anyone knows a better way, and because I couldn't find this exact problem addressed elsewhere.
