I created '--list-dependents' mostly on my way to '--recursive', but I
didn't really like the name either. '--list-transitive' works well for
me.

I also think it would be nice if I would parse the other command line
arguements, remove '--recursive', and pass the rest of them to 'guix
refresh' for each of the (now transitive) packages. Then 'guix refresh
--recursive --update foo' would work as expected™.
