I use Emacs (well, Xemacs, to be exact) and haskell-mode from
somewhere.  It works fairly well (remember to press TAB repeatedly,
until you have the desired indentation!).  Here's what C-h m says:

  Haskell mode:
  Major mode for editing Haskell programs.  Last adapted for Haskell 1.4.
  Blank lines separate paragraphs, comments start with `-- '.
        :
     `haskell-indent', Guy Lapalme
       Intelligent semi-automatic indentation.

     `haskell-simple-indent', Graeme E Moss and Heribert Schuetz
       Simple indentation.

And further down:

  Haskell-Indent minor mode (indicator Ind):
  ``intelligent'' Haskell indentation mode that deals with
  the layout rule of Haskell.  tab starts the cycle
  which proposes new possibilities as long as the TAB key is pressed. 
  Any other key or mouse click terminates the cycle and is interpreted
  except for RET which merely exits the cycle.
  Other special keys are:
      C-c =
        inserts an =
      C-c |
        inserts an |
      C-c o
        inserts an | otherwise =
  these functions also align the guards and rhs of the current definition
      C-c w
        inserts a where keyword
      C-c .
        aligns the guards and rhs of the region
      C-c >
        makes the region a piece of literate code in a literate script

  Note: M-C-\ which applies tab for each line
  of the region also works but it stops and asks for any line having more
  than one possible indentation.
  Use TAB to cycle until the right indentation is found and then RET to go the
  next line to indent.

  Invokes `haskell-indent-hook' if not nil.
