 description in or receive one from a called function, and err_msg_out as a
 char ** for a parameter I write that out to before returning if it's not
 NULL.

 I'm confused then.  What about the err_msg parameters for
 rend_service_parse_intro_for_v* ? They're named err_msg, and declared as
 char **.
