It is a newline in this case and of course one could try to go through 
all source files to find it. However I'm more of the mind that such 
errors (extra lines) can happen frequently and inadvertently, so that it 
makes sense to make them unable to hamper the proper functioning of the 
system wherever such flushing of the output buffers does not have other 
side effects.

Cheers
