cust.vars in manual vs. code

[Karl Berry]

    This is done, in util/txicustomvars.

So I wrote the little doc/refcard/txivarcheck to compare the list of
cust.vars implemented vs. documented.  It reported 46 not documented
(and 160 that were documented; I could see no way to check the other
direction, for variables documented and not implemented, since they
aren't explicitly marked in the manual).

Should any of these be added to the manual, or removed from the code?
(Any that remain can be just excluded from the comparison as a special
case.)

Thanks,
karl
