It would be great to have there but it's out of the
scope of the patch yet.   This is not about add a new dired
feature.  Instead, the target is to turn on a
feature from your shell that is disabled by default.

If you use em-ls you have this feature.  Same as if you use
external program `ls' from zsh or fish shells.
The idea is to let users if they want to enable globstar
in their shell when its disabled by default.

My patch use `file-truename' to get the actual shell
used by `dired-insert-directory'.
