This isn't necessary; you can pass numbers, lists and tuples to the
grass.*_command() functions and they will be converted automatically.

I suggest using the -g flag.

This isn't correct. Without -g, the blank line occurs betwen the
Layer: and Category: lines and the rest of the per-layer information. 
You need to scan through the lines and start a new dictionary whenever
you find a "Layer" line.
