Actually the behavior is even stranger... renaming and then deleting
junctions creates spurious directories.

echo "This is a test file" >| targetfile
mkdir targetdir
echo "This is a test dir file" >| targetdir/targetdirfile

junction.exe junctionfile targetfile
junction.exe junctiondir targetdir

ls -Ag
drwxr-xr-x 1 None  0 2009-11-09 11:56 junctiondir/
-rw-r--r-- 1 None 20 2009-11-09 11:55 junctionfile
drwxr-xr-x 1 None  0 2009-11-09 11:56 targetdir/
-rw-r--r-- 1 None 20 2009-11-09 11:55 targetfile

mv junctionfile newjunctionfile
mv junctiondir newjunctiondir

ls -Ag 
drwxr-xr-x 1 ????????  0 2009-11-09 11:57 junctiondir/
drwxr-xr-x 1 ????????  0 2009-11-09 11:57 junctionfile/
drwxr-xr-x 1 None      0 2009-11-09 11:56 newjunctiondir/
-rw-r--r-- 1 None     20 2009-11-09 11:55 newjunctionfile

junction.exe -d junctionfile
junction.exe -d junctiondir

ls -Ag
drwxr-xr-x  1 None  0 2009-11-09 11:56 newjunctiondir/
-rw-r--r--  1 None 20 2009-11-09 11:55 newjunctionfile
drwx------+ 1 None  0 2009-11-09 12:01 targetdir/
drwx------+ 1 None  0 2009-11-09 12:01 targetfile/

Now this seems to be sheer madness.
The original file and directory names have reappeared!
However 'targetdir' is now empty and 'targetfile' is also an (empty)
directory!


ls -Ag targetdir targetfile newjunctiondir
newjunctiondir:
total 1
-rw-r--r-- 1 None 24 2009-11-09 11:56 targetdirfile

targetdir:
total 0

Interestingly, in Windows explorer, renaming seems to do the right thing -
it renames the target.

Interestingly, Windows explorer allows both file and directory junctions to
be removed (though it displays file junctions as non-openable directories).
Not sure why it does this since I thought junctions could only be deleted
using '-d'.

So it seems to me, we have the following conclusions:
- cygwin treatment of junctions is not consistent with Windows or with
notion of symlinks. It also leaves weird residua after renaming junctions.
- Windows junctions are also messed up but not as much
