This is the problem, I think:

(- (window-body-width nil t)
   (* 2 (frame-char-width))
   (if (and (null shr-width)
            (not (shr--have-one-fringe-p)))
       (* (frame-char-width) 2)
     0))

This kludge is how shr computes how many pixels the window has
horizontally.

Surely there's a better way to find the practical "inner" width of a
window; i.e., the space where we can put text and stuff?  Does anybody
know?
