/* OK, here is a short description of lex/flex rules behavior.
 * The longest pattern which matches an input string is always chosen.
 * For equal-length patterns, the first occurring in the rules list is chosen.
 * INITIAL is the starting condition, to which all non-conditional rules apply.
 * When in an exclusive condition, only those rules defined for that condition apply.
 *
 * Exclusive states change parsing rules while the state is active.
 * There are exclusive states for quoted strings, extended comments,
 *  and to eliminate parsing troubles for numeric strings.
 * Exclusive states:
 *  <xb> binary numeric string - thomas 1997-11-16
 *  <xc> extended C-style comments - tgl 1997-07-12
 *  <xd> delimited identifiers (double-quoted identifiers) - tgl 1997-10-27
 *  <xh> hexadecimal numeric string - thomas 1997-11-16
 *  <xm> numeric strings with embedded minus sign - tgl 1997-09-05
 *  <xq> quoted strings - tgl 1997-07-30
 *
 * The "extended comment" syntax closely resembles allowable operator syntax.
 * So, when in condition <xc>, only strings which would terminate the
 *  "extended comment" trigger any action other than "ignore".
 * Be sure to match _any_ candidate comment, including those with appended
 *	operator-like symbols. - thomas 1997-07-14
