Function svn_opt_subcommand_takes_option 

pub unsafe extern "C" fn svn_opt_subcommand_takes_option(
    command: *const svn_opt_subcommand_desc_t,
    option_code: c_int,
) -> svn_boolean_t

Return @c TRUE iff subcommand @a command supports option @a option_code, else return @c FALSE.

Same as svn_opt_subcommand_takes_option2(), but acts on #svn_opt_subcommand_desc_t.
