Date: Wed, 14 Dec 2011 22:43:52 +0100

Last paragraph of (info "(emacs)Diff Mode") says:

 `M-x diff-show-trailing-whitespaces RET'
      Highlight trailing whitespace characters, except for those used by
      the patch syntax (*note Useless Whitespace::).


But that command is not available (at least for me) from a *Diff*
buffer (from emacs -Q).

2009-01-10  Dan Nicolaescu  <dann <at> ics.uci.edu>

        * diff-mode.el (diff-show-trailing-whitespaces): Remove function.
        Move setting up whitepace-mode ...
        (diff-mode): ... here.
        (diff-mode-menu): Add a menu entry for showing trailing whitespace.


so it is now a menu entry (that runs `whitespace-mode') instead of a
command, and the "Diff Mode" info node should be fixed.

And also etc/NEWS should tell this in "incompatible changes" section.

Fixed, thanks.  I overlooked this when checking the manual.

This was mentioned in the Emacs 23 NEWS, though not as clearly as it
should have been; it was the manual that was behind.
