diff parameters in config file | diff-cmd = bbdiff is a path and not a command

Question

I am trying to get subversion to default to bbdiff for comparing files but I cannot get it to work properly.

The ~/ .subversion/config doesn't seem to like this line

diff-cmd = bbdiff --resume --wait

It looks like 'diff-cmd' is a path and not a command

It half works with the following

diff-cmd = bbdiff

It opens the 2 files but I does not highlights the diffs, as bbdiff needs the --resume --wait options to do this.

any suggestion on how to do this anyone?
