Comment (by simonpj):

 Yes, I think I prefer the `HsPar` approach.  Moreover, if we were to
 display the output of the renamer then this program
 {{{
 f x = g [qq| ...blah... |] x
 }}}
 would display, after renaming, as
 {{{
 f x = g (...expanded quote...) x
 }}}
 where the parens are actively helpful in parsing!

 Let's do that.  Thanks.

 Simon
