Re: void variable

[Richard Stallman]

    Actually, on second thought I am not that sure anymore.  Several
    variables, that are important enough for people to want to bind them,
    are not autoloaded.  The situation is potentially dangerous, as we
    saw with wdired.  So we should warn about it _somewhere_.  Either the
    manual or the docstrings or both.

The manual should direct people to autoload variables used by
autoloaded functions, if programs might want to bind them.
