ghci and user private groups

[Jason Dusek]

  User private groups are not an abnormal configuration, but
  GHCi has such strict security that they are not allowed!

  I appreciate what you guys are trying to do, but I at the very
  least, it should be permitted to use a GHCi that is group
  readable/writable as long as the group name and user name are
  the same. It would be preferable, however, to do away with the
  restriction altogether.
