Could you document this in Documentation/kbuild/kconfig-language.txt
please?  The thing is, I'm not sure it'll work, and it's hard to convince
myself without docs.

Here's what I want:

CRAMFS	FLAT	ZFLAT	outcome
Y	Y	Y	Y
Y	Y	N	Y
Y	M	Y	Y
Y	M	N	Y
Y	N	-	Y

M	Y	Y	Y
M	Y	N	M (*)
M	M	Y	M
M	M	N	M
M	N	-	M

N	Y	Y	Y
N	Y	N	N
N	M	Y	M
N	M	N	N
N	N	-	N

Does dep_tristate give me that?  Particularly the one with a (*) by it.
