By stouset:

My rationale for originally writing the method that way was:

* if the label is provided, use it
* if there is no label, use the default provided by Rails
* if the user passes `nil`, no label text is generated

Admittedly, this method could have used some comments explaining that. Does this patch change that logic? Or is it just a simplification of the original code?
