drh de087bd5ed Clarify the documentation on how comparisons occur in an IN operator.
Fix the comparison operators when both sides of an IN operator are
expressions (ticket ).
Changes to main.mk for adding FTS2 into the standard build also
got mixed in with this check-in by mistake. (CVS 3656)

# Tests in this file are organized roughly as follows:
#
# types2-1.*: The '=' operator in the absence of an index.
# types2-2.*: The '=' operator implemented using an index.
# types2-3.*: The '<' operator implemented using an index.
# types2-4.*: The '>' operator in the absence of an index.
# types2-5.*: The 'IN(x, y...)' operator in the absence of an index.
# types2-6.*: The 'IN(x, y...)' operator with an index.
# types2-7.*: The 'IN(SELECT...)' operator in the absence of an index.
# types2-8.*: The 'IN(SELECT...)' operator with an index.
#
# All tests test the operators using literals and columns, but no
# other types of expressions. All expressions except columns are
# handled similarly in the implementation.
