Judging by its error message, SVN_ERR_RA_NOT_IMPLEMENTED is supposed to
mean "protocol scheme not recognised", not "feature not supported".
I think this should use SVN_ERR_UNSUPPORTED_FEATURE instead, like
svn_ra__assert_capable_server() does.
(There are a few more instances of this mixup in libsvn_ra_svn/client.c.)

... and then the second disjunct here will be able to be removed.
