I get a "permission denied" problem with mv that I don't understand
when using mv to rename a directory.  I have sufficient priveleges to
mv the contents of the directory, and then, when empty, I can mv the
directory.  Why can I only mv the directory when it's empty, while I
can mv the contents of the directory separately?

Here's an illustration; I want to mv directory daily.18 to daily.19:

$ ls # No daily.19 here.
daily.0   daily.11  daily.14  daily.17  daily.3  daily.6  daily.9
daily.1   daily.12  daily.15  daily.18  daily.4  daily.7
daily.10  daily.13  daily.16  daily.2   daily.5  daily.8
$ whoami
rerb
$ ls -ld # I have privs to mess around here.
drwx------+ 21 rerb Domain Users 0 Feb  4 12:40 .
$ ls -ld daily.18  # I've got full perms on daily.18.
drwxr-xr-x+ 3 rerb Domain Users 0 Feb  4 12:56 daily.18
$ mv daily.18 daily.19
mv: cannot move `daily.18' to `daily.19': Permission denied
$ ls -al daily.18 # What's in daily.18?
total 0
drwxr-xr-x+  3 rerb Domain Users 0 Feb  4 12:56 .
drwx------+ 21 rerb Domain Users 0 Feb  4 12:56 ..
drwxr-x---+ 53 rerb Domain Users 0 Dec 18 18:02 home
$ mv daily.18/home . # I can move the contents of daily.18.
$ mv daily.18 daily.19 # I can move daily.18 when it's empty.
$ mv home daily.19 # I can move the contents of daily.18 back into daily.19.
$ mv daily.19 daily.18 # Why can't I move daily.19 back to daily.18?
mv: cannot move `daily.19' to `daily.18': Permission denied
