Gotcha.  I can confirm that
$ apt-cache depends --recurse -i bash libc6 | grep -v '^[<[:space:]]' | grep
libc
is empty, while

$ apt-cache depends --recurse -i libc6 | grep -v '^[<[:space:]]' | grep libc
lists libc6.

Just to explore a bit more:
$ apt-cache depends --recurse -i bash libc6
bash
  Depends: base-files
  Depends: debianutils
  PreDepends: dash
  PreDepends: libc6
  PreDepends: libncurses5

I'm going to check with our local distribution developers and see what's
going on.

It then downloads each one using 'aptitude download'.
