removed a branch

Mostly layout nitpicking but also a micro optimalization:

if() {
   return;
}
// now an else is not required as it will only be invoked if the first
// path is not triggered
// so this change saves a branch altough it is possible that the compiler
// sees this and optimizes this away by itself.
