-Added new member 'query_charset' for bend_initrequest structure. A
-backend init handler should set this member to its native character set
-for query terms. When defined, the frontend server logic will announce
-this character set to a client if the negotiationModel bit is set by the
-client. ALL server implementors are encouraged to specify this. If they
-don't, a warning is issued.
+Changes to generic frontend server interface: added new member
+'query_charset' for bend_initrequest structure. A backend init handler
+should set this member to its native character set for query terms.
+When defined, the frontend server logic will announce this character set
+to a client if the negotiationModel bit is set by the client. All server
+implementors are encouraged to specify this. If a backend server does not
+specify this a warning is issued using yaz_log(YLOG_WARN,..).
Added CCL utility to remove terms (stop words) from resulting RPN
tree. This is handled by functions with prefix ccl_stop_words_ .
