Yeah, I'm less angry at GNU now--I didn't search as hard, but when I found
out 4.3BSD didn't have HISTORY (and neither does 2.11BSD, which is still
actively-ish maintained) then I figured it wasn't something classical that
GNU dropped, just never imported. I feel like it existed on SunOS and
Solaris but I might be wrong about that? Was it really FreeBSD that
introduced it?
