bug#14150: Customize within two Emacs sessions deletes saved customizations

[Barry OReilly]

Open Emacs twice: A then B

In B, customize any customizable variable.  Click "Apply and Save".  Verify init file reflects the save.

In A, customize a different customizable variable.  Click "Apply and Save".  Verify init file reflects the save.  The first customization made from within B is gone, contrary to expectation.
