Jon Ross-Perkins b8ceb8dd8b Print a blank line after a diagnostic. (#3806) 
The purpose of the newline is to make it clearer where a given
diagnostic begins and ends, particularly as the first message of a
diagnostic may not be the error.

This is a trivial code change, but ripples edits through test files.
