IMO the additional line break doesn't really make it easier to read. And note that it is OK now to have code lines longer than 80 chars (as long as they are not longer than 100 chars IIRC), although it is still recommended (but not required any more) to observe the "old" 80 chars length limit. > Although, it would apply to all other long lines in that header, so not > particularly to this $subject.
