+
+ * expr-evl.c: (expr_evaluate) Make expression argument const.
+ Support OP_ADD, OP_SUB, OP_MUL, OP_DIV instead of OP_PLUS, OP_MUL.
+ OP_POW is missing for arg 2 <= 0. OP_LOG is natural log, not
+ base-10 log. Fix OP_ANY, OP_ANY_STRING, OP_RANGE, OP_RANGE_STRING
+ off-by-ones. Add OP_MAX_STRING, OP_MIN_STRING. Fix OP_TIME_HMS,

+ into OP_LTRIM, OP_RTRIM_OPT into OP_RTRIM, OP_NUMBER_OPT into
