This is a great shame. I like OpenBSD's approach to man pages - incorrect documentation is a bug and can be as severe as a bug in code; correct documentation is important.

Fixing up man pages is something that non-technical volunteers could help with, except when it's hard to grok what the code actually does vs what it should do.
