On the one hand, it's hard to justify breaking POLA, and on the
other hand, this program has obvious bugs and gross
inconsistencies between its documented and actual behavior.
If I had the time for it, I'd probably do something sick and
twisted and write a replacement called delta(1). ;-)
In the mean time, I'm happy to apply your suggested change if
you like, but that would only make jot a little bit less wrong.

Thanks. I understand the rounding; I was really looking for a
rationalization of the behavior. Most likely there isn't one. :-P
