breaking out of a while loop

[Duke Normandin <dukeofpurl@...>]

while bottle_count ~= 0 do
  bottle_count = bottle_take(bottle_count)
end
-- the above works

while true do
    bottle_count = bottle_take(bottle_count)
    if not bottle_count then break end
end
-- this one does not.

Semantics of Lua `not'? Thx ...
