Router match with and without trailing slash?

Hey all, ran into a funny one tonight. What are thoughts on matching the router against routes both with and without trailing slashes? For instance, if I add a route like this:

```
app.route('/about, view)
```

… should I expect it to work when navigating to both `/about` and `/about/`? Currently the latter does not. Open to thoughts! I think it’d be useful.

No file or test is identified. Start by locating the router matching entry point and reviewing how the `/about` route is currently compared with `/about/`; done means the project has a decided, tested behavior for both trailing-slash forms.
