Describe variable gives 

,----[ C-h v emacspeak-w3-tidy-html RET ]
| emacspeak-w3-tidy-html is a variable defined in `emacspeak-w3.el'.
| It is void as a variable.
| Documentation:
| Tidy HTML before rendering.
| You can customize this variable.
| [back]

Using customize tells me the variable has been set outside of customize and
changing it with customize may be unreliable. There is nothing in .emacs or any
of my elisp files that changes this variable. 

doing a grep on the *.el files in the lisp dir of emacspeak doesn't show
anything unusual. there is a customize definition with a default setting of t
and there are two 'lets' in webutils.el that set a variable of the same name to
nil, but they are not declared special, besides, nil is not the same as
'void' is it? 

I'm running version 26.0 revision 5118M and emacs from CVS
GNU Emacs (i686-pc-linux-gnu, GTK+ Version 2.10.13) of 2007-08-09 on lion

I'm a bit confused as to how customize can report the variable as being void,
yet also say that it has been changed outside of customize, especially as the
custom type is defined as a boolean and therefore must be nil or t. also, how
can a variable be set \, but still void? confused and a bit out of my depth I
think! Also, once a variable is set to something, how can you then make it
void? wouldn't you need to unintern its symbol?
