> To the extent that the Emacs team still supports --with-ns options as to an older version of OSX (Snow Leopard 10.6.8), this is a "ns-read-file-name" bug report in relation thereto.  The "ns-read-file-name" bug does not seem to affect Emacs running on the current version of OSX (Mountain Lion).

The prompt "yes" or "no" is visible for only a split second, but then disappears.  The default is "yes", which overwrites the existing file (which may not be what the user wants).
