# These test a fixed bug in my regex-tdfa that did not keep the expanded
# form properly grouped, so right association did the wrong thing with
# these ambiguous patterns (crafted just to test my code when I became
# suspicious of my implementation).  The first subexpression should use
# "ab" then "a" then "bcd".

# OS X / FreeBSD / NetBSD badly fail many of these, with impossible
# results like (0,6)(4,5)(6,6).
