Yup.  The added complexity is there because you can gzip (etc) the
files, so nnml has to dance and jiggle around a bit to find the names
of the files.

Or we could just assume that all the articles are in the .overview
file and use that to find out what articles are in the group.  That
should be much quicker, and only slightly less general.
