+** This implementation uses a state machine with 7 states:
+**
+**   (0) START     At the beginning or end of an SQL statement.  This routine
+**                 returns 1 if it ends in the START state and 0 if it ends
+**                 in any other state.
+**
+**   (1) EXPLAIN   The keyword EXPLAIN has been seen at the beginning of 
+**                 a statement.
+**
+**   (2) CREATE    The keyword CREATE has been seen at the beginning of a
+**                 statement, possibly preceeded by EXPLAIN and/or followed by
+**                 TEMP or TEMPORARY
+**
+**   (3) NORMAL    We are in the middle of statement which ends with a single
+**                 semicolon.
+**
+**   (4) TRIGGER   We are in the middle of a trigger definition that must be
+**                 ended by a semicolon, the keyword END, and another semicolon.
+**
+**   (5) SEMI      We've seen the first semicolon in the ";END;" that occurs at
+**                 the end of a trigger definition.
+**
+**   (6) END       We've seen the ";END" of the ";END;" that occurs at the end
+**                 of a trigger difinition.
+**
+** Transitions between states above are determined by tokens extracted
+** from the input.  The following tokens are significant:
+**
+**   (0) tkEXPLAIN   The "explain" keyword.
+**   (1) tkCREATE    The "create" keyword.
+**   (2) tkTEMP      The "temp" or "temporary" keyword.
+**   (3) tkTRIGGER   The "trigger" keyword.
+**   (4) tkEND       The "end" keyword.
+**   (5) tkSEMI      A semicolon.
+**   (6) tkWS        Whitespace
+**   (7) tkOTHER     Any other SQL token.
+**
+** Whitespace never causes a state transition and is always ignored.
