No, better to start off with (d-New) and add all seven staffs
dynamically.

It will be from tomorrow's build (d-AddMirrorVoice 1) to add a mirror
staff of staff 1.

not exactly a dummy, the script until now just checked if the parameter
was true. Everything in Scheme is true except for #f which is false. I
called the parameter 'staff (which in Scheme means the symbol named
staff) as a hint as to what passing it would do, which is make a staff
rather than a voice. When you invoke any command from a menu it is
always passed the parameter #f; what I have now done is to make the
scripts take action if passed a number (rather than #f or a symbol or
the string "edit" or, indeed, anything else).
