Why is this taking a boolean indicating if does anything. Why can't the caller
just check it?

Well, mainly because I wanted to preserve the call structure. Although it does
indeed make more sense not to call it in such situation, period. Changed as
suggested. 

 
 // Shows a prompt UI to set the default browser on first run
 // (if necessary and permitted).
