I agree. Not because it could be slower, but I don't think scanning 
shelf is so necessary. Especially when there are several files 
specified in the command line. What if some files have patches on 
shelf, and some haven't? What bzr should print in such case? Things 
very quickly become very tricky. Let's keep it simple.
