main-is argument cannot be hierarchical module

Foobar.hs:

module Foo.Bar where
main = putStrLn "hi"
ghc --make -main-is Foo.bar Foobar -o Foobar
Warning: output was redirected with -o, but no output will be generated

When not using hierarchical names, i.e. name Foo.bar FooSomething and -main-is FooSomething, a binary FooSomething is created.

Reported for 6.9, but probably also in 6.8.
