| When we get the tokss from her-parser's ready, they're a bit cluttered.  I'm not sure what Dr. McBride had in mind when he made that mess.  But this doesn't mater, from this clutter we can create a list of lines which is aware of haskell's brackets.  If a multi-line clause is inside brackets, then we keep the whole section in the same "line".
