 create_delimiter

 Generate a new (null-terminated) string that does not exist in  query 

 and is therefore suitable for use as a query delimiter.  Store this

 delimiter in  delimiter_buff .

 

 This is quite simple in that it doesn't even try to parse statements as an

 interpreter would.  It merely returns a string that is not in the query, which

 is much more than adequate for constructing a delimiter.
