create a diff: namespace and redirect it to a diff url. http://en.wikipedia.org/w/index.php?&diff=prev&oldid=300616445 would become [[diff:300616445]]
Was chatting with BC about this earlier, a couple of notes: * It would probably be best as a namespace, not an IW link. Relative IW links would be pretty straightfoward and could be shipped with default MW, but they might be broken (related: bug 18664 and bug 19270). Fully qualified URLs are not friendly for something like this, nor would they be quick to implement in a large-scale installation a la WMF. * A pseudo-namespace (similar to Special: at -1 and Media: at -2) would be better than a normal one, as it eliminates chances of collisions with existing namespace definitions.
Note that MobileFrontend has diffs as a special page, you can create an interwiki to it, for example: https://en.m.wikipedia.org/wiki/Special:MobileDiff/592700201...592717598
