Revision 20389 fills out cultshorts.txt to have all 666 pockets.
I discovered the bugbear-in-the box while I was doing that, before I (just now) read you helpful comment. 
This is raw data and undoubtedly has some typos in it, which I will discover and fix when I write a module to parse this data file.
There are also some (possible) data errors in the spreadsheet:
	
	
	
		Code:
	
	
		159	Effect	Ocelot Eyes (0)
165	Item	line	star (3)
166	Item	line	star (3)
270	Effect	Very Clean Teeth (90)
509	Effect	Jittery (90)
578	Candy	chocolate filthy lucre
591	Candy	chocolate filthy lucre
647	Effect	Cold, Dead Hands (0)
	 
 - Those are the only 2 effects that grant more than 80 turns of an effect.
- That is the only candy that appears twice
- Somebody didn't put in effect durations for two effects
- I find it odd that two adjacent pockets give exactly the same line.star drops
Here is how I tagged the various kinds of result:
	
	
	
		Code:
	
	
		# Stats	MUSCLE	MYSTICALITY	MOXIE
# Effect	EFFECT (DURATION)	EFFECT (DURATION)...
# Buff	EFFECT (DURATION)
# Drugs	EFFECT (DURATION)
# Lozenge	EFFECT (DURATION)
# Joke 	JOKE    (implies Joke-Mad (20)
# Item	ITEM	ITEM...
# Avatar	ITEM
# Bell	ITEM
# Booze	ITEM
# Candy	ITEM
# Chess	ITEM
# Chocolate	ITEM
# Currency	ITEM
# Fruit	ITEM
# Oyster ITEM
# Pixel	Item
# Yeg	Item
# Scrap	NUMBER	(demon name puzzle)
# Poem	MESSAGE	(waterlogged poem)
# Meat	MEAT	CLUE	(meat-wrapped puzzle)
	 
 A Buff is 20 turns of an Accordion Thief buff
Drugs give you 40 turns of The (Wisdom, Style, Strength) ... of the Future, as opposed to numerous Effect resuts that give 20 turns of one of those and also some other effect.
Lozenge gives you 40 turns of The Halls of (Muscularity, Mysticality, Moxiousness, as opposed to numerous Effects that gove 20 turns and also some other effect.
Currency is an item you can "use" to get Meat
Chocolate is one of the chocolate-covered tools. The game says "oh, candy" when you open the pocket - but they are special
Lots of effects have a single source with that effect alone and mutiple sources with that effect and another one. The single effect always has a longer duration.
I don't know where this is all going, but this is all the useful data, to my eye, from the spreadsheet.
