# The test itself is working properly. The problem is that stock SCCS
# does not preserve executable permission on files under its control, so
# the test is correctly failing.
#
# The GNU version of SCCS does provide an 'x' flag[1] for compatibility
# with SCO OpenServer which enables executable permission preservation.
# However, I haven't convinced myself that it would make sense to put in
# the work to add executable-preservation support to the SCCS backend
# for these special cases (GNU CSSC and SCO OpenServer).
