I don't think this is currently implemented but it might not be too
difficult to do. As far as I can see the code in foreign already knows
how to read the stuff, it just never gets copied into R variables. 

The internal format is somewhat different from R's idea of a factor,
but it should be workable:

Essentially there's a list of label records, which each have a list of
<value, label> pairs, and an associated list of variables (in index
form) to which the format applies.

Any takers?
