Doing a quick a quick tail on all the source files for dmd, 
druntime and phobos, I only found 6 source files that ended in a 
curly brace and 2 ending in a 'g'. All others ended with a 
newline. Its certainly not required but it is common in the style 
guides I've seen and I personally have my editor automatically 
insert a newline.
