Better yet, drop the support for interpreting the '.' as anything but
a hierarchial module namespace separator.  That is, use this:

>       [ d ++ mod2dir nm ++ e | d <- dirs, e <- hugsSuffixes ]

The last release rightly supported both old and new style names.
We're already committed to dropping the non-hierarchial libraries
in future releases.  Let's drop non-hierarchial names too.

[I also lean towards dropping the implicit search of the current
directory too but I'm not certain enough of the consequences of such a
change.]
