Ideally, even this rather trivial code is best left outside of ERB 
files.  Hide this away in a function and it can be as clean and 
multi-liney as you want and doesn't muck up your ERB files.  This is 
doubleplus true if this code is used more than once.  Cramming the 
entire if statement onto line just makes it less readable.
