5690	Use os.path.dirname() not os.path.join(foo, '..')	Thomas Güttler <hv@…>	nobody	"If you use symlinks to directories using "".."" will lead you
to the wrong directory.

Here is an example:
mkdir -p /tmp/dotdot/two
ln -s  /tmp/dotdot/two/ /tmp/symlink
cd /tmp/symlink
ls ..
 --> two
 Content of /tmp/symlink, not /tmp!
