O.K. :)

Looks good in principle, but I think there's an API compatibility problem.

You can't do that. This is a public struct that gets allocated
elsewhere, so you can't change it in a minor release.

I think you'll have to rev svn_ra_open and svn_ra_plugin_t::open and add
the progress_func and progress_baton parameters there. Should be fairly
easy to do.

(Note that svn_client_ctx_t is different, we have an allocator function
for it.)

You don't need the cast here. Sorry, couldn't resist the style nit. :)
