	ACK, thanks!

	Shouldn’t it rather be defcustom?

	I’d also ask for a separate “do not override” value.  That is:

   (shr-width (if (DO-NOT-SET-P eww-rendering-width)
                  shr-width
                eww-rendering-width))

	(And, similarly, defcustom’s :type above being a ‘choice’.)

	Shouldn’t this rather be ‘error’?
