Change `cp` to terminate with an error when attempting to copy through
a dangling symbolic link with the `--force` option. Before this
commit,
touch src
ln -s no-such-file dest
cp -f src dest
would incorrectly replace `dest` with the contents of `src`. After
this commit, it correctly fails with the error message
cp: not writing through dangling symlink 'dest'
