r1.89 of channel.c introduced it. I've gone back through various
combinations, reverting to r1.88 and stepping down to r1.20 of buffer.c
and r1.7 of buffer.h "fixes" the problem. Note that this wasn't
introduced in the buffer.* changes as I've downgraded just those and run
with a fresh channel.c.

My understanding is that Cameron acknowledged this on IRC a few days
ago, but will unfortunately be busy for a while yet. Orion turned in his
bit for safekeeping recently too. I've been in contact with Mathew, so
hopefully he'll be able to figure something out.
