For now, I suggest reverting the changes to the printing flags, and
thinking about a print= option instead. AFAICT, backwards
compatibility requires that the printing flags remain a mess.

One consequence is that you will need to duplicate printwindow.c. 
Trying to make one version handle both the existing mess (which
essentially dictates that certain combinations of switches will print
various pieces of information in entirely different formats) and a
sane system will result in unmanageable complexity.
