It is there for debugging purposes.  I usually use the if(0){} construct
when some variable is used by the contents.  This eliminates compiler
warnings.  Usually, the formatting is sufficiently painful that I leave
the potential code in so that it does not need to get rewritten.

So let's leave if(0) in.
