Not quite.  I am saying the draft should start where the Scheme starts, which
is in this case on the second line.  It should not concern itself with the
mechanisms, such as #!, that the host system use to decide where the Scheme 
starts.  It should not even mention them.

My comment perhaps did not quite fit into the context - sorry for the 
confusion.
