    Bart> The above will complete to produce command lines like

    Bart> xxx co co2 construct cons1 cinema
    Bart> xxx construct cons2 cinema co co1
    Bart> xxx co co2 ci construct cons1 cinema co co1

That works.  But my situation is a little different, what I would like
is to have "co1 co2 co3" be part of the completion words as long as
there is a word "co" in front, i.e.,

      xxx co co1 co2	       or
      xxx co co3 co1 co2

Do c[offset,string] require a fixed offset or can be a range?  Use -1
as offset will only work for the 1st word.  Also, I still want to be
able to complete the 'construct'.  Any option left?  Thanks...
