[NTG-context] Problems with texexec & pdfarrange

[Sanjoy Mahajan]

> texexec --pdfarrange --paper=A5A4 --print=up  live.pdf

It needs to be given as '--paperformat'.  I'm pretty sure '--paper'
gets disambiguated as --paperoffset, so ConTeXt looks for a dimension
but gets "A5A4", and then complains about a missing number.
