"Run Ediff on a pair of regions in specified buffers.
-Regions \(i.e., point and mark\) are assumed to be set in advance except
-for the second region in the case both regions are from the same buffer.
-In such a case the user is asked to interactively establish the second
-region.
+Regions \(i.e., point and mark\) can be set in advance or marked interactively.
This function is effective only for relatively small regions, up to 200
