In luatex, function show_node_list() displays the nodes of a discretionary
in a different order than pdftex. Is this intended? I'm especially
missing the number of nodes of the replacement (in the example: 2).
Example:
\showboxbreadth=\maxdimen
\showboxdepth=\maxdimen
\tracingonline=1
\newbox\mybox
\setbox\mybox=\hbox{\discretionary{aa}{bb}{cc}}
\showbox\mybox
\bye
Output of luatex:
.\discretionary replacing
..\tenrm c
..\tenrm c
..\tenrm a
..\tenrm a
.|\tenrm b
.|\tenrm b
Output of pdftex:
.\discretionary replacing 2
..\tenrm a
..\tenrm a
.|\tenrm b
.|\tenrm b
.\tenrm c
.\tenrm c
Ciao
