Subject: Fix handling of family instances in the presense of this doc stuff
X-Git-Url: http://git.megacz.com/?a=commitdiff_plain;h=f39ff24bc78da5ba09db8864ecbd7d1055b332db;hp=f39ff24bc78da5ba09db8864ecbd7d1055b332db;p=ghc-hetmet.git

Fix handling of family instances in the presense of this doc stuff
- Not sure whether I do the right thing, because I don't understand the
  doc stuff.  However, the original code was definitely wrong and
  breaking the renaming of family instance declarations.
- The important point is that in

    data instance T pats = rhs

  T is *not* a defining occurence of T (similarly as C is not a defining
  occurence in "instance C Int").
