athena.plugin.set_plg_cmd_dir expects right now one or more directories separated by empty spaces which is not a typicall way in an Unix environment and will break on directories containing empty spaces.
So instead of relying on empty spaces athena should expect a ':' separated list in ATHENA_PLG_CMD_DIR and the athena.plugin.set_plg_cmd_dir and athena.plugin.get_plg_cmd_dir method documentation needs to reflect that.
