Hi,
I was scratching my head for a while trying to remember why I wanted
do remove margin_kern_node while unboxing. Then I found the following

| Hm. What part? breaking apart boxes are a problem anyway, since marks and
| specials interfere. I suggest:
|
| (1) keep the nodes there when unvboxing
| (2) discard them when unhboxing (the lines of such an unvboxed box)
|
| There's a lot of stuff around that unvboxes, like multi column routines! I

| if you have a margin_kern node, then can you also add: \nomarginkern (like
| the proposes etex primitive \noligs) which means: don't kern the next char,

It is interesting to remove that part as Hartmut did, and see what
surprises it can bring :).
