Should --dynamic-list affect garbage collection?  If so, what about
--dynamic-list-cpp-new, --dynamic-list-cpp-new, and --dynamic-list-data?

I'm thinking the next thing you'll see is a complaint that
--dynamic-list now unexpectedly prevents garbage collection, for
someone using a wildcard in their dynamic-list file.
