Hi. The info manual of Diffutils, in the Overview node, talks about the 'M-x compare-windows' Emacs command. For more information it refers to the Emacs manual node 'Other Window'. However, the aforementioned command is not described in that manual node. It is instead described in '(emacs) Comparing Files'.
I am sorry for not providing a patch. Regards -- - I am Brazilian.
