Haddock's -s switch is broken

[Peter Simons]

Hi,

it appears that the '-s' switch in the CVS-HEAD version of
Haddock stopped working the way I know it. I run

  haddock -h -s . *.hs

to generate the documentation, and it does have the "Source
Code" link on every page, but the link points to the "."
_directory_, not to "./{module-name}.hs" file like it
should.

Am I doing something wrong or is this a bug?

Peter
