    todo: aggressively ignore more data from todo
    
    The todo module has an optimization to avoid lots of small strings being
    allocated. In doing so, we potentially pull in data that we cannot know
    we need to ignore until after it has been delivered from the subprocess.
    
    This tries to ignore node_modules, a commonly used directory for npm
    dependencies from even beeing scanned by grep.
    
    Related to #509
