  Log Message:
  -----------
  Suppress pedantic diagnostic for a file not ending in EOL (#131794)

WG14 added N3411 to the list of papers which apply to older versions of
C in C2y, and WG21 adopted CWG787 as a Defect Report in C++11. So we no
longer should be issuing a pedantic diagnostic about a file which does
not end with a newline character.

We do, however, continue to support -Wnewline-eof as an opt-in
diagnostic.
