I thought I saw an error here when list-directory with a directory (not
file) glob (ex: ~/Project/emacs/*/) is followed by another list-directory,
but I think the actual issue is that the default directory in the first
case is set to something that doesn't exist, which messes up call-process
in the second invocation of list-directory. The error I saw was:

Debugger entered--Lisp error: (file-missing "Setting current directory" "No
> such file or directory" "/home/chadpbrown/Project/emacs/*/")
>   call-process("ls" nil t nil "-CF" "--"
> "/home/chadpbrown/Project/emacs/src/")
>   insert-directory("/home/chadpbrown/Project/emacs/src/" "-CF" nil t)
>   list-directory("~/Project/emacs/src/" nil)
>   funcall-interactively(list-directory "~/Project/emacs/src/" nil)
>   call-interactively(list-directory nil nil)
>   command-execute(list-directory)


I'm not sure it's worth the overhead to fix this. I'm testing a small
change that replaced default-directory in list-directory
(lisp/files.el:7387) with

            (if (file-exists-p default-directory)
                default-directory
              user-emacs-directory)

..but it feels like a hack?
