c06e371f55 Rather to my surprise given the amount of testing this code has had, 
Kevin Lyles spotted a tree234 bug! copytree234() segfaulted when
asked to copy a tree containing no elements, due to failing to allow
for the case that t->root might be NULL. Fixed, and added a
regression test.

2bef4dfb50 Yikes! I've only just noticed that this copy of tree234.c was still 
using unwrappered malloc/free, leaving plenty of openings for out-
of-memory segfaults. Switch to using Puzzles's memory management,
which I should have done right at the start but can only assume I
forgot about.
