[PATCH] Feature request PR14331: add -W(no-)eof-newline

["Dave Korn" <dave dot korn at artimi dot com>]

    Hi gcc-patches@,

:ADDPATCH cpp:

ref: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=14331

  Here's the patch as promised that implements the new warning option to
suppress the "No newline at end of file" warning message.  It's modelled on
the -Wendif-labels option, in particular the fact that -pedantic enables it
even if it's been turned off by an earlier option (and that a later option can
disable it again).

  It comes with documentation and testcases.  Bootstrapped and regtested on
x86_64-unknown-linux-gnu in C,C++ and Fortran, with no regressions, and
bootstrapped and tested for correctness on i686-pc-cygwin in C,C++ and
Fortran.

  Ok to checkin?
