Cheat sheet for opendir()

[John Esak]

Ahh, good picking... It just shows how you can fool yourself with bad
testing.  Before I posted that, I tested on both Unix and Windows. On Unix I
used a directory called /tmp/test which I made for the purpose of the test.
Then, Windows I made a directory called c:\test and ran the same opendir(),
it of course returned "." and "..".  Never thought about opening a root
folder.  Thanks.
