Traverse the node list of a paragraph before line break from head
to tail in sequential order, recursing into sublists where they
appear. The callback removes and inserts nodes: which ones
depends on the nodes already processed (has a state).
Using the previous example code,
\startfoo
a\hbox{b}c
\stopfoo
should result in the traversal <glyph a>, <hlist ...>, <glyph c>.
