Mo,
Excellent. I've applied your patch with the exception of the
SVN_ERR_ALREADY_PRINTED, which I had to whip up myself (you didn't
provide a patch to include/svn_error.h). This works very nicely, and I
nthink it's definitely more flexible than what we currently have.
I'm probably going to take the help strings out of main and put them
into the respective client files... there's no reason for it to be all
lumped together in main.
Cleaning up nicely...

This wasn't provided for in the patch, so I went ahead and hacked
something together.
