Josh,
I decided to go with your original recommendation of using std::max(1,
alignment) for each block calling set_alignment. It's not really the
set_alignment functions job to make a decision on what the caller
meant when they passed in a number; it just protects against incorrect
values. The guy that calls the set_alignment function should make sure
it's passing the right value.

It's a bit more work this way (although mostly I expect people to
copy-and-paste), but this makes more sense.

Thanks,
Tom
