I just realised pandoc refuses to set paper size to A4 if I specify "-V papersize:A4", I have to use "-V papersize:a4". This makes sense from the point of LaTeX or ConTeXt, but perhaps not from the point of the user, where the real world paper format is called A4 and not a4.
Perhaps pandoc should treat paper sizes case insensitive, i. e. convert any value to lower case?
