TWINE: LBA: Asking about pirate recipes results in stuck dialogue

[antoniou79]

This is tested on Windows 10, on ScummVM 2.9.0git (from recent master HEAD) on the GOG version of the game.

I am attaching a saved game. You start at the entrance of the library and you have to go to the elephant NPC that sits and reads a book outside the projection/theater room. He's the only one who will respond to Twinsen's inquiry and propose to recite three different passages from the book.

If Twinsen asks about Pirate Recipes, the NPC will make a joke, but then if you keep pressing space, the dialogue will "continue" infinitely with empty dialogue boxes.

The user can get unstuck if they press Esc through.

This bug does not happen with the other dialogue options.
