/* We need to use this because using NLST gives us more stuff than
 * we want back sometimes.  For example, say we have:
 *
 * /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.
