Using subprocess.call() with shell=True is no better than using
os.system(). Both should be avoided at all costs.
The grass.script module provides a number of convenience functions
which use grass.script.make_command() to generate the command's
argument list from the function's argument list. Also, they use a
version of subprocess.Popen() which has been wrapped to deal with some
of Windows' idiosyncrasies.
