Currently, space-preserver tokens inside NCV expressions use the "SPACE" token type indicator whereas other spaces are not marked up at all. We should use one convention for all space tokens to simplify the SQL-building process. Let us use the former convention; it is preferable that everything in the parsed string belong to some token.
Checkin # bb977c8 fulfills this task. All spaces are marked up in the preprocessing phase, and the main state machine passes these tokens to the final output stream unchanged.
