 * aLeft; aRightEnd similarly marks the end of aRight.
 *
 * The function assumes that aLeft < aLeftEnd and aRight < aRightEnd.
 *
 * The function stores the addresses of the next characters in the sequence
 * into aLeftNext and aRightNext.  It's up to the caller to make sure that the
 * returned pointers are valid -- i.e. the function may return aLeftNext >=
 * aLeftEnd or aRightNext >= aRightEnd.
 *
 * If the function encounters invalid text, it sets aErr to true and returns
 * false, possibly leaving aLeftNext and aRightNext uninitialized.  If the
 * function returns true, aErr is guaranteed to be false and both aLeftNext and
 * aRightNext are guaranteed to be initialized.
