Re: Close .emacs file after customization?

[Richard Stallman]

    You will get a warning if customize *does not* kill the .emacs buffer
    after saving customization, which is currently the case, but that is
    precisely what the original poster wanted to change.

If Emacs already has a buffer visiting .emacs, and that file has
changed on disk, visiting it again will ask whether to reread the
file.  The only advantage of killing the buffer is that you won't have
to answer that question.  Is that a major advantage?

We could make Custom kill the buffer if it didn't exist before
Custom created it.
