New Debug method Debug.Assert doesn't print out any default message to console if the message is not provided.

1. Open scene.
2. Add script to camera.
3. Play.
4. Assert going to throw error as it should be. However when you use Debug.Assert(bool), default message is empty.

Method Output to console:

"
UnityEngine.Debug:Assert(Boolean)
Test:Update() (at Assets/Test.cs:18)"
(Notice the upper empty line)

I know its not really a big deal, but still some default message would be better, than just simple empty line.
