I found this is what intended. This should be documented as comments. |2) users and user-groups only requires special handling and behavior as follows | Normal user : | A. unquoted ( USER ) will be treated as user ( downcase ). | B. quoted ( "USeR" ) will be treated as USeR (case-sensitive). | C. quoted ( "+USER" ) will be treated as normal user +USER (i.e. will not be considered as user-group) and case-sensitive as string is quoted. This seems confising with the B below. This seems should be rearranged. | User Group : | A. unquoted ( +USERGROUP ) will be treated as +usergruop ( downcase ). | B. plus quoted ( +"UserGROUP" ) will be treated as +UserGROUP (case-sensitive). > This is why you simply continued processing for '+"' without > discarding and skipping the '+', and not setting in_quote so the > following parser code works as it is not intended.
