        src/bin/sh: show.c

Log Message:
This change affects shells compiled in DEBUG mode only, for normal
shells (anything made by build.sh) there is no change at all.

In DEBUG shells, when tree dumping, remember to include NNOT (same
omission as was just corrected in jobs.c :1.81) - of course, here there
are lots of other node types not handled as well.

ALso, avoid a core dump bug when doing a tree dump of a pieline
where the commands are not all simple commands (which can only
happen with a command string like " cmd | ! cmd | ... ".  The "!"
in the middle is utter nonsense, and should be forbidden, but
for now, at least avoid a core dump.
