Elijah Newren 0201fcfc6c Stick an emacs comment directive at the beginning of all the code files so 
2006-10-01  Elijah Newren  <newren gmail com>

	* src/*.[ch]: Stick an emacs comment directive at the beginning of
	all the code files so that people using emacs will be more likely
	to get coding style correct in their patches.  We still need a
	similar vi directive.  #358866
