*
* /a (directory)
* /a/b (directory)
* /a/b/b1
* /a/b/b2
* /a/b/b3
* /a/c (directory)
* /a/c/c1
* /a/c/c2
* /a/c/c3
* /a/file
*
* If you did an "echo /a/<star>" in a normal unix shell, you would expect
* to get back /a/b /a/c /a/file. But NLST gives back:
*
* /a/b/b1
* /a/b/b2
* /a/b/b3
* /a/c/c1
* /a/c/c2
* /a/c/c3
* /a/file

* So we use the following routine to convert into the format I expect.
