While doing that, if you could also please fix the relation between
module <m> and module <m>-tests?

$ ./gnulib-tool --extract-dependencies hamt-tests
hamt

$ ./gnulib-tool --extract-dependents hamt
(none)

The latter invocation should list hamt-tests.

And then, before simplifying, it would be useful to optimize
--extract-recursive-dependents. Currently

$ ./gnulib-tool --extract-recursive-dependents stdlib

does not complete within a reasonable time.
