[NTG-context] blank page in doublesided mode

[Alan Bowen]

In doublesided mode ConTeXt seems to insert a blank page at the end of 
a document when there is an odd number of printed pages. I have checked 
the English documentation and so far I have only found out how to force 
a page in order to produce an even paged document.  I have yet to come 
across anything that seems to show how to stop ConTeXt from adding a 
blank page. Any pointers will be very gratefully received.
