Date: Fri, 9 Jun 2017 19:08:27 +0100

- Make one PATH member non-readable

	$ chmod -r /path/to/some/bin/folder

- Start `emacs -Q`.
- M-x shell
- Press "e<TAB>" (any letter will do)

I get the following error:

	(file-error "Opening directory" "Permission denied" "/path/to/some/bin/folder")

While a warning could make sense, a non-readable folder should not prevent
completion from working.
