It already does this.

Given

$ find . -print
.
./a
./a/z
./a/z/b
./a/z/b/c
./a/x
./a/x/b
./a/x/b/c
./a/x/b/c/d
./a/x/b/c/d/1
./a/x/b/c/d/4
./a/x/b/c/d/3
./a/x/b/c/d/2
./a/x/b/c/d/5
./a/y
./a/y/b

Running `echo a/*/b/c/d/*' calls opendir(2) twice:

$ ./bash ./x1
opendir: a/
opendir: a/x/b/c/d
a/x/b/c/d/1 a/x/b/c/d/2 a/x/b/c/d/3 a/x/b/c/d/4 a/x/b/c/d/5
