* Width of the body of a map using PERSEC characters per sector.

* One row shows WORLD_X/2 sectors, separated by one space. Requires
|
|
* WORLD_X/2 * (PERSEC+1) - 1 characters.
|
|
*
|
|
* Every other row is indented so that the center of the first sector
|
|
* is aligned with the space separating the first two sectors in the
|
|
* adjacent rows. For odd PERSEC, that's (PERSEC+1)/2 additional
|
|
* characters. For even PERSEC, it's either PERSEC/2 or PERSEC/2 + 1,
|
|
* depending on whether we align the character left or right of the
|
|
* center with the space (the map will look rather odd either way).
|
|
*
|
|
* We need one more character for the terminating zero.
