Added the -h (header) option; it prefixes the unlit'ed output with a pair
of line pragmas, e.g.,

  foo$ unlit -h foo.lhs foo.lhs - | head -3
  # 1 "foo.lhs"
  {-# LINE 1 "foo.lhs" #-}
  module Foo where
  foo$

Using -h saves the main user of 'unlit', GHC, from having to do the
prepending of line pragmas via shellular magic. (=> GHC is able to
drop the dependency on there being a UNIX-like shell underneath when
using System.system).
