Log Message:
lint: fix parsing of chained assignments (since 2021-07-15)
The grammar rule for assignment_expression is quite different from those
of the other expressions, for 2 reasons: first, its precedence is
right-to-left. Second, its left-hand side must be an lvalue, which
rules out all binary operators. K&R C even had a grammar rule named
'lvalue' for this purpose. Later C standards made the kinds of
expressions more fine-grained and used 'unary_expression' in this place.
