Daniel C. Sobral 8ac94f5119 Good thing about these examples is that no one uses them, so they can
stay broken for months without anyone noticing.

The boot-conf command was changed as to reproduce the behavior of builtin
loader words precisely. As a result, it now always need an argument, possibly
0 indicating that no other arguments are being passed. This broke in a
non-deterministic way (ie, it could go on working as if everything was fine).
