I agree about must_be_updated_p. I had exactly same though that it is
redundant with redisplay flag when reading the code.

prevent_redisplay_optimizations_p is intuitively logical, but I still
feel confused because it appears to be redundant upon seeing redisplay
flag in the buffer. It raises a question what redisplay flag really
means - it is causing redisplay of a window/buffer or not necessarily?
