Add new tests using cp's --rem option.

Reflect the fact that cp's -f option no longer causes cp to remove the
destination file before trying to open it.
Reflect the fact that `cp -bdl' now makes a backup when copying a
symlink onto the file it points to (FIXME: look into this, and why
cp -bl does *not* do so).
