I don't know.  I just noticed how SDL differs from Java on this point.  
In Java the newlines don't matter; they're just whitespace, except with 
the single-line comments.  But in SDL the newlines also separate 
children, so they must be parsed at the syntactic level.

In other words, I haven't given this enough thought, so I'll stop 
commenting.
