Good point!

It looks like the builtin echo in /bin/sh is the one with the
problem:

user at host[70] /bin/sh
sh-3.2$ /bin/echo -n FOO
FOOsh-3.2$ echo -n FOO
-n FOO
sh-3.2$ 

Though, according to the FreeBSD echo(1) manual page, printf(1)
instead of "echo -n" should be used for maximum portability,
so I am inclined to just use "echo" instead of "/bin/echo -n"
or printf(1).

Thanks,
Pavlin
