We removed the cap on the buflen size (although if someone gives
something insanely large, it can get capped), so EINVAL will only
happen for unknown flags. I'll fix the suggested man page.

P.S. The reason why OpenBSD had a very strong opinion about returning
EIO for buflen greater than 256 bytes was they really wanted to pound
it into application writers than if they were trying to fetch more
than 256 bytes, they were probably Doing Something Wrong, and they
decided EIO was less subtle that EINVAL....
