Summary: "-M" option broken with "-hisuf prof.hi"

Initial Comment:
The "-M" option doesn't work if you try to use it in
combination
with the "-hisuf" option where (as suggested in the
documentation) the "-hisuf" option value ends in ".hi".

For example, 

        ghc -M -hisuf bar.hi  Main.hs

will result in a Makefile which contains dependencies
of the form

        # DO NOT DELETE: Beginning of Haskell dependencies
        Main.o : Main.hs
        Main.o : ./Bar.bar.bar.hi
        # DO NOT DELETE: End of Haskell dependencies

Notice that the suffix used in the Makefile is
".bar.bar.hi".
It should be ".bar.hi".

Here's the example sources that I used to reproduce the
problem.

$ cat Main.hs
import Bar
main = Bar.main

$ cat Bar.hs
main = return ()

Fixed, thanks.  Workaround is to use a -hisuf with no dots
in it.
