the class RulesTest method checkEmpty.

/**
 * Check if this rule would match an empty way.
 *
 * Such rules are not allowed.
 *
 * The problem case is length().  The length of the test way is 3.3 and we always make
 * sure that length is only used in expressions with GTE and values of 1 or 2 so they
 * are always true.  However if there is a NOT in front if it it will then be false and
 * so the simple test of of an empty way returning true could miss this case.
 *
 * So we also check with a way of length zero.
 *
 * Then there is still the problem that we do not detect an expression such as (length()>=2 & !(length()>=2))
 *
 * So reject any rule that has length() beneath a not.
