[Haskell-cafe] GHCi 6.6 tab-completion of source file paths not working.

Hi. I've just installed GHC 6.6 on an amd64 running a gentoo linux distribution. With GHCi from 6.4.2 I could run "ghci" then do Prelude> :l Foo/Bar.hs by hitting tab after Foo to complete the path to Bar.hs This no longer works, hitting tab only shows what's in the pwd. If I run "ghci Foo/Bar.hs" then I can :r fine and I can do a :l Foo.Bar using tab-completion to complete the module name. Tab completion of in-scope functions looks to be working fine. Has anybody else experienced this problem? Thanks Daniel
