OK but (info "(coreutils) Backup options") should also link back to the exact
cp -b spot, else most folks will miss it.

P.S., There _is_ an easier way of making backups of several files,
But there is a bug, one has to do it one at a time despite -b. Bug bug bug. 

$ \cp -fb h k l .
cp: `h' and `./h' are the same file
cp: `k' and `./k' are the same file
cp: `l' and `./l' are the same file
$ \cp -fb h h
$
