Re: Documentation for custom-file - is not (load custom-file) needed?

    2.  Maybe the docstring should warn the user to use an absolute file
        name.  (This may not be obvious at all to a beginning user.)  Very
        confusing things can happen if a relative file name is used when
        setting this through Custom with a bad default-directory.

I will explain that in the doc string.

    3.  The last paragraph fails to point out that if you set `custom-file'
        through Custom, Custom will automatically copy your
        `custom-set-variables' and `custom-set-faces' forms to
        `custom-file'.  (But it will not erase them from .emacs or the old
        `custom-file'.)

If it is smart enough to do this, it could also delete them from
the old custom file.  Would you like to implement that?
