Simply injecting $location anywhere in your app breaks anchor links (which up till now have been working for 20 years!). Here is example code demonstrating the issue: https://gist.github.com/skivvies/7125406

Here is a rawgithub link so you can actually run this code: https://rawgithub.com/skivvies/7125406/raw/b42a135b7a40db7dc00a7726fa8efd080e14b7b7/index.html

Please keep an eye on the browser's address bar when you click "link to anchor". Compare this to almost the exact same code, with the only difference being that $location is not injected: https://gist.github.com/skivvies/7125477

Again, here is a rawgithub link to this version so you can run it: https://rawgithub.com/skivvies/7125477/raw/1b4a4d2692616c42b92b813b4c7d1e26ffe38c9b/index.html

Reproduction steps:

1. Open a new browser window directly to an anchor on a page with an Angular app that injects $location, e.g. https://rawgithub.com/skivvies/7125406/raw/b42a135b7a40db7dc00a7726fa8efd080e14b7b7/index.html#anchor
2. Angular hijacks the url's hash and rewrites it to add a leading slash, e.g. https://rawgithub.com/skivvies/7125406/raw/b42a135b7a40db7dc00a7726fa8efd080e14b7b7/index.html#/anchor
3. The browser does not scroll the page down to the linked-to anchor
4. Clicking any links on the page to the anchor (e.g. the "link to anchor" link in the example code) also fails to scroll the page to the anchor

(I hit this because I'm using angular-bootstrap's dropdown toggle directive which injects $location, I don't ever actually inject it into my app, but simply depending on angular-bootstrap is enough to break my anchor links. Thanks to this post for tipping me off. /cc @pkozlowski-opensource)
