Ways of interfacing with externals diff tools should be improved.

I like the suggestion of having a way to tell svn "you just tried the
external diff but that didn't work so use internal diff please".
That's much easier and straightforward than devising clever schemes
for selecting a diff tool based on the value of some svn: property
or filename extension, for instance.
