Are you joking? 40 files on my machine, and over 250 calls to
insert_before and insert_after, but I must admit that they're not latex
files and probably do a-typical things.
I think inserting a node at the end of a given head node is something
different than inserting a node exactly after a given node. I you want
to do the former, you could always say
insert_after(node.tail(head), new)
that inserts a node at the end of a list starting with head which is not
always the same as inserting after head
quite some callbacks expect a head to be returned and get a head passed, so
head = node.insert_after(head,somenode,newnode)
is pretty standard and catches the cases where head == somenode which
saves some testing. Of course you can always do it the manual way: by
assigning next/prev fields.
