It seems a bit strange to have the platform logger support this but not 
SimpleFormatter. Do you think there would be any compatibility concerns 
if SimpleFormatter were changed to emit one line output? If not then it 
might be simpler to change it along with the platform logger so that 
this property isn't needed. If there is a concern then an alternative it 
to change the platform logger so that it emits the one-line output by 
default as it's only used in the platform.
