I just got what you're trying to say. Unfortunately, your quotes mislead
me about what you were concerned about. You're right, the man page
doesn't explicitly state whether anonymous mappings are zero filled or
not. Since man pages prioritize concision, I would expect the page to
explain how anonymous mappings are different from other mappings, but
not how they are the same.
