bug#1171: ns-version-string

[Glenn Morris]

Please consider fixing the NS implementation of x-server-version to
return a list of three integers, as it is documented to do (xfns.c,
w32fns.c).

It's getting a bit ridiculous seeing all the Emacs.App bug reports with

  Windowing system distributor `Apple', version  
  97.112.112.108.101.45.97.112.112.107.105.116.45.57.52.57.46.51.53
  configured using `configure  '--with-ns''

(Again, this comes from M-x report-emacs-bug.)

Thanks.
