When you look at the subversion sources, you see in subversion/svn/main.c:1936 
the call svn_cmdline_set_up_auth_baton() use opt_state.config_dir. This gets 
set by svn_config_ensure() some 400 lines above - which has a scary comment 
there.

In the FSVS sources there's racallback.c - which has the call to 
svn_cmdline_setup_auth_baton() in it.
This call gets a config directory (currently only NULL), and a "svn_config_t 
*cfg" - which is something different from the "apr_hash_t *cfg" that 
svn_ra_open() wants (in url.c). The config hash already gets fetched by 
svn_config_get_config(), like svn does - but again with a config directory as 
parameter.
