// "B.384[V.100] = 1" in NUTCracker syntax.
//
// Var[100] is supposed to be a value between 0 and 8, but it's also used for
// the verb ID, which is between 120 and 128. In other versions, the scripts
// subtract 120 before setting the bit, the the Sega CD version does not. This
// means that the Sega version uses bits 504 through 512 instead of bits 384
// through 392.
//
// While most conversations probably only clobber a few of these flags, the
// following things may be impacted:
//
// 504 - Saying "Geeze, what an obvious sales pitch." to Cobb.
// 505 - Saying "You know, you really should quit smoking." to Smirk.
// 506 - Something unknown around the line "I give up!  You win!"
// 507 - unused
// 508 - Saying "I need a ship." / "Can you guys crew a ship?" to the cannibals.
// 509 - Saying "Money.  I want money." to the cannibals.
// 510 - Saying "What's in your standard potion of exorcism?" to the cannibals.
// 511 - Saying "Where is he hiding it?" to the cannibals.
// 512 - Saying "How do I get to these catacombs?" to the cannibals.
//       This is also unavailable if Herman already told you.
//
// We're just lucky the bug didn't impact anything more important than this,
// because the bug is literally in hundreds of places throughout the game. And
// just to rub it in, the Sega version doesn't even seem to use these flags for
// the conversation trees.
//
// Fortunately, this is the only places in the game where the bit variables are
// set in this particular fashion, so we can detect and correct for it. Though
// old savegames will of course still be impacted.
