I have CDPATH defined in .bashrc

It is
":~:/home/data1/protected/Work/3rd-Dynamic/Corporation/Division_4/Dept_10/Company
 Formation"

Then I start: emacs -q

then: cd tmTAB it works, it expands to tmp and I enter tmp

Initially I am in directory /home/data1/protected

if I am in tmp, after cd .. I come back to /home/data1 instead of
/home/data1/protected

then after cd .. if I wish to come back to home I can do cd ~ which
works.

But then if I wish to cd tmTAB this expansion does not work anymore.
