Changes (by simonpj):

  * status:  new => closed
  * testcase:  => indexed-types/should_fail/T4246
  * resolution:  => fixed


Comment:

 Your (very resonable) request pushed me over the top to doing a
 significant re-organisation of `TyCon.lhs`.  But then it was easy:
 {{{

   * Improve pretty-printing of family instances

   Fixed Trac #4246

     M ./compiler/types/FamInstEnv.lhs -8 +16
 }}}
 So it's done.

 Simon
