I think "proper largefile support" is pretty much the standin handling
we already have. It is quite important to not just leave them out; an
unreliable diff is bad. Being able to see that a largefile changed is
often quite valuable.
Largefiles are in general so large that it could be a problem to copy
them out to temp files just for diffing ... and they are often binary
and not really diff-able anyway.
I can however also see the use case for tools that can compare images or
archives so I guess it would be nice to have both options somehow ...
