What I'm seeing is that **/file in my example, or dir/**/subdir in
your example, acts as if a single * glob had been used.  I.e.
you get (dir/link/subdir) because dir/*/subdir would have matched that,
and I get (dir/file link/file) because */file would have matched that.

With just those two examples, it looks like ** tries to match like
a regular * first, and then only tries recursion if that fails.
