Seems I misremembered. Two reported bugs in find, but didn't want to get yelled at (again) so did not report the cat one. Cat -n is not in any standard, but at least in my opinion there's no way openbsd's behaviour on "cat -n a b" when "a" doesn't end in a newline is desired.
Yup, they did merge both find bugs.
The ignored ones seem to be my reported doas bug (not security problem, but directly contradicts manage about a config keyword detail) and efiboot.
IIRC the latter bug was like... this can never have worked.
I just checked the GitHub mirror, and those two are still not picked up.
