The attached patch is an updated version of an earlier patch which I submitted. 
It adds a cheap but sub-optimal pedestrian routing option:

  --route-pedestrian-areas

When this option is set, mkgmap will add a pedestrian way around the perimeter 
of pedestrian areas (Squares and Plazas). This will allow GPS devices to 
calculate routes through (i.e., on the perimeter of) such squares to other 
connecting ways. This is not the best solution, as you will always be routed 
along the edge of the area, but it works. I have been unable to think of a 
better, practical solution.

The code is in the style of (read: shamelessly copied from) Mark's cycleway 
additions.

I have been using the patch for some time, and I have found it quite useful for 
pedestrian routing in cities where such areas frequently occur.

Your feedback and comments would be appreciated.

Cheers.
