Undex W2K 
mv --help which prints 
	mv (GNU fileutils) 3.16
It also creates junk\junk until it fails 
producing

C:\thisisalong\junk\junk\junk\junk\junk\junk\junk\junk\junk\junk\junk\junk\junk\junk\junk\junk\junk\junk\junk\junk\junk\junk\junk\junk\junk\junk\junk\junk\junk\junk\junk\junk\junk\junk\junk\junk\junk\junk\junk\junk\junk\junk\junk\junk\junk\junk\junk

Noticed by someone else and passed onto me:

Create a directory with long name:

mkdir thisisalong
cd thisisalong
mkdir junk
mv junk junk

This will create junk\junk\... nesting until it fails.

If you do the test under a short name it seems to work correctly (gives
a message about cannot move 'junk' to a subdirectory of itself).

I have verified this behavior under Win98 and Windows 2000 using an older
copy of the filutils - but I am told it is seen on newer versions as 
well.

A quick look at copy.c source seems that 'copy_into_self' flag doesn't
work properly if path contains long names.
