Using -L or --limits, the south bound uses the west value.

[Lyceq]

Using the latest code (as of 10/1/2010) on a Debian GNU/Linux x86_64 system. Rendering using the command './maps/c10t --world world.offline --limits -20,5,-25,45 --threads 5'. The resulting map extends 45 chunks in both the west and south directions. Debugging shows that the values are being parsed correctly (min_x = -20, max_x = 5, min_z = -25, max_z = 45).

Executing c10t with different values for south has no effect on the map. Using different values for west affects both west and south.
