So, are you saying that if the user has a (client-side) custom diff
program installed, that case 1 will behave (possibly radically)
differently from 2 and 3?
This seems like a misfeature. Why not check out the revisions into
temporary files and then run the client-side diff? Slightly more
inefficient, perhaps, but cooperates much better with the user's
preferences. (The 'efficient' way to do this is to generate *svn* diffs
between revisions, apply them to the working copy to create a pair of
temporary files, and *then* run the user's 'diff' program on the pair.
This way you get the efficiency of the server-side approach (since the
server "knows" the diffs) with the consistency of the client-side model.)
