[GRASS5] a shy question about nullvalue

[Andrea Antonello]

Hy folks,
When a raster map is created, the range is written to file in cell_misc.
Since that is given from the start, why using the second map defining the 
null-values instead of simply defining a null-value outside of that range for 
every map?
With the growing size of files nowadays I think reading the file twice (normal 
+ nullplaceholder) and then compare them could get a long job.

Let's not argue about who should implement this :) For now it's just a easy 
question and couriosity.

Cheers 
Andrea
