Update route.js

[yentheo]

feat(ngRoute): change

This change adds a new event on ngRoute called beforeRouteChange. With this change it is possible to cancel a locationChange based on route data. The problem that I am trying to fix here is described in #5581

Well the build failed because of the comments being too long. Don't know how to make a new commit with the comments made shorter though.

Do I need to do a new PR from the original branch? Can't I just change my original commit an create a new commit for that change?

You can use git rebase.
