"svn diff a b" doesn't mean "compare a with b and show the
differences". It means "compare a with the repository location for a
and show the differences, and compare b with the repository location
for b and show the differences". And there aren't any so it doesn't
show anything.

I haven't used the --old and --new flags so I'm not sure about this
usage.

I think that's correct, those are your options.

I don't think of this as a limitation but rather you're just trying to
use "svn diff" for something it wasn't designed to do. It was designed
to do what I explained above.
