This is looking very nice.  I can certainly see grafting the guts from the
current sh.c into this, and having your parser become the new heart of sh.c
This conde certainly enjoys the benefits of hindsight (i.e. carefully designed
for the task at hand from the start).  The current sh.c is much more
evolutionary (i.e. lots of ugly hacks as I retrofitted things into it).  I'll
look over this further (perhaps when I get bored at my wife's family's
christmas party ;-) and see what I can do to finish up redirects and such.  I
really like what I have seen of this so far.
