  21 # Tar 1.26 had problems extracting from incremental restores when given
  22 # the -C option.  The code in incremen.c:try_purge_directory and
  23 # misc.c:remove_any_file was using savedir(), which ignored eventual changes
  24 # in the current working directory and caused the malfunctioning.
  25 #
  26 # The problem was reported by Piotr Rotter on 2013-03-22.
  27 #
  28 # This testcase is based on scripts provided by Piotr Rotter and Nathan
  29 # Stratton Treadway.
