That doesn't make it belong in status directly... How does it work in
combination with --show-updates (or -u)?

I agree that it is a useful question to answer in some way, but that doesn't
make it directly belong in status... In my eyes diff is a better fit.
Perhaps it can be added in 'svn' itself, if we determine that it is a
logical operation from 'svn'... But in both libsvn_client, and libsvn_wc I
don't see a relation with any of the other feature of status.
(Note that this is the same way as --diff is implemented for log in 'svn'
itself)
