<p>The function combines the two lists <em>list1</em> and <em>list2</em> by moving all elements from <em>list2</em> into <em>list1</em>, so that all elements are still sorted.

The sorting order in which the elements of <em>list2</em> are inserted into <em>list1</em> is determined by the comparison function <em>compare</em>.
