[jhc] darcs patch: Improve lambda/pi printing code

Fri Apr 11 19:01:59 EDT 2008 Samuel Bronson * Improve lambda/pi printing code Only only put as many lambda/pi abstractions on a line as will fit. Use sortKindLike to get the uppercase lambdas for type variables of kind other than *. (For instance, * -> *.) I had to make E.TypeCheck, E.Eval and E.Subst import E.Show with a {-# SOURCE #-} pragma before I could use sortKindLike. (I also had to write the .hs-boot file, of course).
