cp -rl dir dir in 7.1 not so great

[Mikael Magnusson]

In my old 6.x something, cp would just say
  cp: cannot copy a directory, `dir', into itself, `dir/dir'
(it would still do it, but only once)
In 7.1 I get a result like this:

% timeout 1 cp -rl dir dir
% ls -R dir|wc -l
1063

Without the -l it still behaves properly.
