Commit 773ac4a broke support for route parameters that are not seperated
from other route parts by slashes, which this change fixes. It also adds
some documentation about path parameters to the when() method and
escapes all regular expression special characters in the URL, not just
some.
Previously one had to write:
$routeProvider.when('/foo', {...});
$routeProvider.when('/bar', {...});
$routeProvider.otherwise({...});
After this change it's just:
$routeProvider.
when('/foo', {...}).
when('/bar', {...}).
otherwise({...});
Breaks #when which used to return the route definition object but now
returns self. Returning the route definition object is not very useful
so its likely that nobody ever used it.
