Here's a possibly more useful demonstration:

wooledg:~$ mkdir /tmp/x; cd /tmp/x
wooledg:/tmp/x$ mkdir dir; ln -s dir link; touch dir/file
wooledg:/tmp/x$ shopt -s globstar
wooledg:/tmp/x$ echo **
dir dir/file link
wooledg:/tmp/x$ echo **/file
dir/file link/file

I think the complaint is about the handling of "**/file" here.
