Yes, in my first posting on the subject to which James Lowden refers:
  http://lists.gnu.org/archive/html/groff/2010-01/msg00007.html
(which was sent at the "alpha" stage of the technique) I had indeed
put an extra " character at the end of each .ds statement. These are
not necessary (end-of-line is enough) and can indeed cause trouble!

If you go to the "next-in-thread" for that posting:
  http://lists.gnu.org/archive/html/groff/2010-01/msg00008.html
you will see them without terminating " characters:

ds rotate "\X'ps: exec gsave currentpoint 2 copy translate \
\\$1 rotate neg exch neg exch translate'
.ds restore "\X'ps: exec grestore'

I think the first version (with ") was an oversight!

Best wishes to all,
Ted.
