a %include {...} directive on line one, make that directive the header for
the generated C file. (3) Enhance the lemon.html documentation.

DISTINCT by B-Tree by half, under the assumption that the DISTINCT will
eliminate about half the rows of output. This is really a wild guess. But
we do not have any better way of estimating what the row-count reduction due
to DISTINCT will actually be.

range scan. The subsequent OP_IdxGT will always catch the NULL. Similarly,
omit the not-NULL check on the lower bound of a reverse index range scan,
as the SeekLE opcode will disallow the NULL.

postpone doing the main table seek until after all WHERE clause constraints
have been evaluated, in case those constraints can be covered by unused
later terms of the index, thus avoiding unnecessary main table seeks.

been processed. This obviates the need for the WHERE_SEEK_TABLE and
WHERE_SEEK_UNIQ_TABLE flags to sqlite3WhereBegin() and the ensuing
complication, and it allows the covering index optimization to be used
further into WHERE clause processing.
