O.K., one more pitfall.  Obviously, the shells use their own internal
echo and don't call /bin/echo.  sh and dash give me

$ echo -ne "\033" | od -x
0000000 6e2d 2065 0a1b
0000006

i.e. echo is actually echoing the switch "-ne", followed by a space,
ESC and newline.  In bash, I get

tom@tom-desktop:~$ echo --version
--version
tom@tom-desktop:~$ /bin/echo --version

I'll be using /bin/echo now to make sure the same echo is used in bash and sh.
