I don't think this is likely to be the problem, since Stewart's
neat reversal transformation should only affect left-right, and not
top-bottom.

But, while I'm at it: Stewart's suggestion:

   For A4, all you need do in the page setup is:

   -1 1 scale
   595 neg 0 translate

needs to be done for each page in groff output. The simplest way to
ensure this is to find the section near the beginning of the file
which reads

  /BP{
  /level0 save def
  1 setlinecap
  1 setlinejoin
  72 RES div dup scale
  LS{
  90 rotate
  }{
  0 PL translate
  }ifelse
  1 -1 scale
  }bind def

and modify this to read (inserting the two lines shown by -->)

     /BP{
     /level0 save def
     1 setlinecap
     1 setlinejoin
     72 RES div dup scale
     LS{
     90 rotate
     }{
     0 PL translate
     }ifelse
     1 -1 scale
-->  -1 1 scale
-->  LS { 841.89 neg 0 translate }{595 neg 0 translate} ifelse
     }bind def

which will left-right reverse all portrait AND landscape pages
as read.
