I can't comment on the code, but the grammar on the comments caught my eye:

> +/* Can any range from range_box does not extend higher than this
argument? */
>

>+}

The sentence sounds quite garbled in English. I'm not entirely sure what
it should be, but given the comment below "/* Can any range from range_box
to be higher than this argument? */" maybe something like:

/* Does any range from range_box extend to the right side of the query? */

If used, an analog wording should be used for overHigher2D's comment like:

/* Does any range from range_box extend to the left side of the query? */

Also:

/* Can any range from range_box to be higher than this argument? */

should be:

/* Can any range from range_box be higher than this argument? */

Another question: Does it make sense to add the "minimal bad example for
the '&<' case" as test case, too? After all, it should pass the test after
the patch.

Bets regards,

Tels
