Log message (5 lines):
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.

Modified files:
U   puzzles/tree234.c
