AT_SETUP([incremental restores with -C])
AT_KEYWORDS([incremental extract incr07])
# Tar 1.26 had problems extracting from incremental restores when given
# the -C option. The code in incremen.c:try_purge_directory and
# misc.c:remove_any_file was using savedir(), which ignored eventual changes
# in the current working directory and caused the malfunctioning.
#
# The problem was reported by Piotr Rotter on 2013-03-22.
#
# This testcase is based on scripts provided by Piotr Rotter and Nathan
# Stratton Treadway.
