On the other hand, think about all the systems with a /etc/rc.local
which have lines like this:

if [ -f /usr/local/bb/ ]; then
        /usr/local/bb14b/ start
        echo -n 'bigbrother'

And there are thousands of opensource packages that use "echo -n" in
the many versions of configure that are out there.

A "man echo" on a Solaris box will show you some confusion.
