[R] strip.custom() with more than one conditioning variable

Thanks Duncan, but it's of no use.  It still leaves space for two
strips and doesn't use the first one.  I don't actually want a style =
4.  I used it as an example of when a factor.levels vector might be
wanted.  In my case I want a vector of expressions which can't be made
factor levels.  If I didn't need to show two conditioning variables,
I'd have no problem.

I need to work out how which.given is meant to be used.  It doesn't
make sense to use it the way I have and I'll desist as soon as I find
out how to use it properly.
