The initial value doesn't matter:
- This bit is only needed when the buffer is displayed in a window and
only if that window's `redisplay' bit is itself equal to `false'.
- At the time the buffer is created it's not shown in any window.
- Whenever we change which buffer is shown in a window, we set that
window's `redisplay' to `true'.
So if you want to initialize it, feel free. `false' is a good initial value.
`true' is also a good initial value.
