Renew any annulled message tokens in the current context
Description:
Any
message tokens which have been annulled (by a call to MSG_OUT, ERR_REP, etc.) are renewed unless
any new token value has been defined (using MSG_SETx, MSG_FMTxetc.) since the previous tokens
were annulled.
The intended use of MSG_RENEW is to allow a set of message token values to be used repeatedly in a
sequence of messages without having to re-define them each time.
