Closing this PR. We are that we want api for canceling the route change, but it's not that simple (we need to revert the $location), so here is an issue for that: #592

[bartes]

Currently in our project we are reverting location url in more less this way

this.$on("$beforeRouteChange", function(scope, next, current, stopCallback) {
if (!current){
self.lastUrl = $location.url();
return;
}

if (next && userWantToGo()){
  self.lastUrl = null;
} else {
  stopCallback();
  $location.url(self.lastUrl);
}

});

It could be integrated inside $route service.

yep, the problem is, when route change is induced by outside change (browser's url change) - e.g. user has typed into address bar or clicked on link (in hashbang $location mode)...

We have to consider these cases as well...
