Ludovic Courtès 9132b9bd72 nar: 'restore-file-set' registers the temporary result as a GC root. 
* guix/nar.scm (temporary-store-directory): Use 'add-indirect-root', not
  'add-temp-root'.  Reported by Andreas Enge <andreas@enge.fr> at
  <https://lists.gnu.org/archive/html/guix-devel/2014-04/msg00161.html>.

Mark H Weaver d2d8779b21 Work around behavior of old 'scandir' in Guile 2.0.5. 
Problem reported by John Darrington <john@darrington.wattle.id.au>.

* guix/nar.scm (write-file): Filter out "." and ".." from the result of
  'scandir'.  Previously we did this by passing a suitable predicate.
