Window width to use for HTML rendering.
May either be an integer specifying a fixed width in characters,
or nil, meaning use the full width of the window.
If shr-use-fonts is set, the value is interpreted as a multiple
of the mean character width of the default face's font.
Also see shr-max-width.
This variable was added, or its default value changed, in Emacs 25.1.
Probably introduced at or before Emacs version 28.1.
