• CTFcreateMessageContinued can now be called without providing the multiline header.
• The 'current' multiline header is stored as a static variable in ctformatting.c.
• The functions CTFcreateMessage(Begin)(Loc) assign the multiline header.
• CTFcreateMessageEnd frees the multiline header and sets it to NULL.
• The CTFcreateMessageBegin functions call CTFcreateMessageContinued to parse remaining_lines instead of returning them unparsed.
• Updated tests for the changed behaviour.
