Yes, as long as you have a 'base' version to diff against.  I'd probably
try something like:

    p4 diff2 -du //depot/vendor/freebsd/head/... //depot/user/ed/mpsafetty/...

The only tricky part with diff2 is that it expects depot-based paths, as
it runs the diff `in the server', not against local workspace files.
