2. scp host1:/tmp/a host1:/tmp/a

    # ls -lart /tmp/a
   rw-rr- 1 root root 0 Aug 19 08:51 /tmp/a
3. cat /tmp/a 

1. rpm -qa | grep openssh
   openssh-8.7p1-45.el9.x86_64
   openssh-clients-8.7p1-45.el9.x86_64
   openssh-server-8.7p1-45.el9.x86_64

   Expected results

Not to delete the file contents. This looks to be a regression with the move to sftp since this does not occur when you use the `-O` parameter.

Note, this is not a practical thing to do, but it broke some automation we had so probably better to fix it.
