I discovered a new bug (new to me, anyway). If you are building a worker or settler, then unhappy people don't consume any food.
E.g., suppose your city is size 6, with 4 happy people and 2 unhappy people, and suppose the 4 happy people are working tiles (plus the city center) that generate 16 food and 6 hammers. Then, you have a food surplus of 16-12 = 4 (assuming no unhealth), so, if you're building a settler, you should get +10 hpt (4f 6h). But you actually get +14 hpt (8f 6h); the food required to feed the two unhappy people is not counted against you.
(This is in 1.61; I haven't tried it in Warlords.)
