Michael Gmelin 731704f5ea bsdinstall: Fix installation script splitting
This allows writing setup scripts that contain lines starting with
"#!", e.g., a shebang when creating a shell script using cat:

    #!/bin/sh
    echo "Populate rc.local"
    cat >/etc/rc.local<<EOF
    #!/bin/sh
    echo booted | logger -s -t 'example'
    EOF

Prevent accidentally running a setup script left behind by a
previous invocation of bsdinstall.
