OK, now I have a clearer idea of what you're trying to do. I must
admit that it seems you're pushing the restrict and exclude parameters
farther than I've seen them used before. I can't think of any better
examples offhand, and in fact, the only way I can see to do multi-level
restricts of this sort, beyond two levels, would be either to use a
wrapper script to combine multiple input parameters together to build
up a restrict list for htsearch, or to modify htsearch to support a
multi-level restrict scheme.
