[NTG-context] Missing <space> in gs.rb from recent con-tmf.zip

The line in scripts/context/ruby/graphics/gs.rb with -dSAFER needs a <space> before the closing quote. The corrected line is: arguments << "-q -sDEVICE=pdfwrite -dNOPAUSE -dNOCACHE -dBATCH -dSAFER " -- George N. White III Head of St. Margarets Bay, Nova Scotia
