I agree -- there should be one (1) function that takes care of drawing 
the headerline. this could get ouf-of-control easier when done different
ways in places far, far away...

now that I think of it, narrowing may not bring any advantage, but function
which writes headerline to current (point) -- when doing initial drawing
nothing has to be done beforehand, in case of updating, first delete line
and then redraw...
