 * This is somewhat ugly.
 *
 * Given a header ("Resist", e.g.), a list ("Fire", "Cold", Acid", e.g.),
 * and a separator character (',', e.g.), write the list to the spoiler file
 * in a "nice" format, such as:
 *
 *      Resist Fire, Cold, Acid
 *
 * That was a simple example, but when the list is long, a line wrap
 * should occur, and this should induce a new level of indention if
 * a list is being spread across lines. So for example, Bladeturner's
 * list of resistances should look something like this
 *
 *     Resist Acid, Lightning, Fire, Cold, Poison, Light, Dark, Blindness,
 *       Confusion, Sound, Shards, Nether, Nexus, Chaos, Disenchantment
 *
 * However, the code distinguishes between a single list of many items vs.
 * many lists. (The separator is used to make this determination.) A single
 * list of many items will not cause line wrapping (since there is no
 * apparent reason to do so). So the lists of Ulmo's miscellaneous traits
 * might look like this:
 *
 *     Free Action; Hold Life; See Invisible; Slow Digestion; Regeneration
 *     Blessed Blade
 *
 * So comparing the two, "Regeneration" has no trailing separator and
 * "Blessed Blade" was not indented. (Also, Ulmo's lists have no headers,
 * but that's not relevant to line wrapping and indention.)
