Right, the information column data is built up from the info_str, which looks
at data that was put into the ncp_tree. It will be difficult to change
because we're using the ptvc_* routines to semi-automatically add data to the
ncp_tree... most of the NCP dissector is table-driven. We don't ever have
the interesting data in hand. By "interesting data" I mean the data that goes
into the info column string. That's why we consult the ncp_tree, via the
finfo's.
