-very wide frames, HTML text will be rendered more narrowly, which

+*** New variable 'shr-max-width'.
+If this variable is non-nil, and 'shr-width' is nil, then SHR will use
+the value of 'shr-max-width' to limit the width of the rendered HTML.
+The default is 120 characters, so even if you have very wide frames,
+HTML text will be rendered more narrowly, which usually leads to a
+more readable text.  Set this variable to nil to get the previous
+behavior of rendering as wide as the window-width allows.  If
+'shr-width' is non-nil, it overrides this variable.
