Does the comment provide some useful extra information that isn't
obvious?

All these &=~ things seem redundant.

I think we need to come up with a way to eliminate this horrible
repetition. But that can be done as a cleanup later.

What's with the extra |= on all of these?
Why not just initialize the thing with the proper value from the start?
