[Message part 1 (text/plain, inline)]

Hi,

If a folder has a file "a.b", I can't create a folder named "a.b" in the
same parent folder.

Here is how to recreate that in an "emacs -Q" session:

> emacs -Q &
C-x C-w C-a C-k ~/.emacs.d/test.el
M-: (make-directory "~/.emacs.d/test.el")

Doing so gave me the below error.

Unix allows have a file and a directory with the same name in the same
parent folder. I believe that the distinction between an existing file or
an existing directory is not being made here.
