Is there a GNU Emacs interface to 'diff' that works sort of like 'grep'?
For example, one might type:

        M-x diff foo bar

and it would start up a diff process in the background, such that each time
you hit next-difference (the equivalent of next-error), you would be shown
the two files foo and bar in two windows, each positioned at the next
difference found.  (This is a generalization of the compile command, where
you're running some command (diff) with two arguments instead of one.  I
suppose you could generalize this further to n arguments.)

Alternatively, a next-difference command for compare-w.el would be useful
too, although I think the diff interface would be nice in its own right.

If you have something like this (or are now inspired to write it), please
send me a copy.

Thanks in advance.
