rmdir ../dirname starts removing "." when it shouldn't. The following shell
script demonstrates the bug.

cd /tmp
mkdir q		# make a test directory for safety
cd q
mkdir qq qr	# some junk directories
cd qq
>qqq		# a junk file

rmdir ../qr	# this seems to try to remove "." and fails
ls		# fails since "." has been removed from /tmp/q/qq
# cd ..		# fails since ".." has been removed from /tmp/q/qq
		# last line is commented out since it causes the
		# shell itself to exit - another bug?
cd /tmp/q
ls qq/*		# fails
ls qq		# works
rm qq/*		# fails
rm qq/qqq	# works - bug is not fatal since explicitly named files
		# can be copied to safety
cd /tmp
rmdir q/qq q/qr q	# clean up
