Something fairly interesting:

$ mkdir foo
$ mkdir foo/bar
$ ls -dl foo/bar
drwxr-x--x 1 cjoan cjoan 0 Mar  1 14:31 foo/bar
$ ls -dl foo
drwxr-x--x 1 cjoan cjoan 0 Mar  1 14:31 foo
$ echo "test" > foo/bar/baz.txt
$ echo "somestuff" > foo/bar/somefile.txt
$ ls -dl foo/bar
drwxr-x--x 1 cjoan cjoan 0 Mar  1 14:31 foo/bar
$ ls -dl foo
drwxr-x--x 1 cjoan cjoan 0 Mar  1 14:31 foo
$ rmdir foo/bar
rmdir: failed to remove `foo/bar': Directory not empty
$ ls -dl foo/bar
drw------- 1 cjoan cjoan 0 Mar  1 14:32 foo/bar
$ ls -dl foo
drwxr-x--x 1 cjoan cjoan 0 Mar  1 14:31 foo


The rmdir fails of course, but it also changes the permissions.
So I take it that git always runs an rmdir on the parent directory
when it removes a file?  Seems like it would be a sensible way to do
it on a system without this behavior.
