/**
* insert_list() -
* p points to a list of dict_nodes connected by their left pointers.
* l is the length of this list (the last ptr may not be NULL).
* It inserts the list into the dictionary.
* It does the middle one first, then the left half, then the right.
*
* Note: I think this insert middle, then left, then right, has
* its origins as a lame attempt to hack around the fact that the
* resulting binary tree is rather badly unbalanced. This has been
* fixed by using the DSW rebalancing algo. Now, that would seem
* to render this crazy bisected-insertion algo obsoloete, but ..
* oddly enough, it seems to make the DSW balancing go really fast!
* Faster than a simple insertion. Go figure. I think this has
* something to do with the fact that the dictionaries are in
* alphabetical order! This subdivision helps randomize a bit.
