#1802: Change in input for graph function in r.mapcalc

The input for the graph function in r.mapcalc is a string with XY values,
like:

"newmap = graph(map, x1,y1, x2,y2,... xi,yi)"

Often, X and Y values are available as separate columns or vectors. In
such cases, it would be much easier if X and Y values can be given as
separate vectors, e.g., something like:

  "newmap = graph(map, x1,x2,x3,x4,...xi, y1,y2,y3,y4,...,yi)"

Glynn Clements has already created a patch to implement this, see
http://lists.osgeo.org/pipermail/grass-dev/2012-November/060851.html. I
would like to suggest to implement this patch which will add a graph2()
function with the above syntax
