Yes, insert_before and insert_after also fix next and prev pointers.
It depends on your style of programming what you prefer: manual pointer 
fixes or the prebuilt function (myself, I usually adjust pointers 
manually, but sometimes the functions are more convenient as then you 
need to deal with two travelling nodes instead of three).
