Sure.  So my first question boils down to which of the two alternatives
below does the community prefer?  (To be clear about the intended
semantics: this is the application of the function f to the arguments x, y,
and z.)

    f x
    y
    z

or

    f x
     y
     z

Both are correct, in most contexts.

And then there's the second question: if the second alternative is
preferable, is there a way to get haskell-mode to do it automatically?  As
it is, it refuses to indent y any farther to the right than in the first
alternative.  I can space it in by hand, and then haskell-mode puts z under
y, but that's annoying, and it gets in the way of reindenting large regions
of code automatically.
