Subject: 28.0.50; M-x shell: there is no completion after cd ..
Date: Thu, 01 Oct 2020 19:50:45 +0300

I have noticed that there is no completion in M-x shell after I do the
cd ..

Example:

cd t<TAB> will give me: cd tmp

then I am in ~/tmp directory, then I do: cd ..

then if I wish to do again cd t<TAB>, there is "no match" notification.

It looks as bug to me.

Works here.

I'm quite sure this is something specific to your system's
configuration, symlinks, etc.  It is not a general problem.

I have found out that if I delete the CDPATH variable, before starting
emacs -Q, then this is not taking place. You probably have

My CDPATH is as following:

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

And it works well in bash without Emacs, not in M-x shell.

So if I do not have CDPATH, it works well, but if I do have, it does
not work.

Still a bug. It should work.
