EZ> Because that's not really a "failure": the file was already there.

OK, but, the shell says 1, not 0:

$ ln -s ~/mln -s ~/mapping/aiyongxian/aiyongxian.kml /tmp/
$ cp ~/mapping/aiyongxian/aiyongxian.kml /tmp/; echo $?
cp: '/home/jidanni/mapping/aiyongxian/aiyongxian.kml' and '/tmp/aiyongxian.kml' are the same file
1

Also
>> (file-error Input and output files are the same Success /home/jidanni/mapping/aiyongxian/aiyongxian.kml /tmp/aiyongxian.kml)
should be
>> (file-error Input and output files are the same. Success. /home/jidanni/mapping/aiyongxian/aiyongxian.kml /tmp/aiyongxian.kml)
But that doesn't make sense either.
Obviously the word Success has been stuck in the middle, and should be
moved to the front or back. And in fact changed to Failure.
