r.diversity.py is broken on Windows:

    home = os.path.expanduser('~')
    rlidir = os.path.join(home, '.grass7', 'r.li')

The script tries to create an r.li subdirectory, but fails because the
parent directory doesn't exist.

$HOME/.grass7 is correct for Unix, but on Windows it's
%APPDATA%\GRASS7. From lib/init/grass.py:

    # configuration directory
    grass_env_file = None # see check_shell()
    if sys.platform == 'win32':
        grass_config_dirname = "GRASS7"
        grass_config_dir = os.path.join(os.getenv('APPDATA'), grass_config_dirname)
    else:
        grass_config_dirname = ".grass7"
        grass_config_dir = os.path.join(os.getenv('HOME'), grass_config_dirname)

I have added that in r60403.

Sandra, please try the updated version from Addons SVN.
