paths with multiple *s should cause warning

[appsforartists]

For curiosity's sake, I tested what would happen if you had this path:

  <Route
    path    = "/example/:keyName/*/*/"

and tried to transitionTo it. Splat gets put in twice:

http://localhost:8080/example/4025675/grandpa%2Cmom%2Cme/grandpa%2Cmom%2Cme/

Since that is most likely gibberish, developers who use multiple *s should be warned that this makes the correct resolution of transitionTo ambiguous.

This may have been fixed in the latest builds. See #317.

I'd have to see what your transitionTo looks like, but the router will throw an error if you don't give it enough splats.

Let me know if you think this should be reopened.
