When the f0, f1, f2 capabilities were deleted from getty(8) with the COMPAT_43 removal, some dead code was forgotten and the gettytab(5) man page wasn't updated.

(Adding trasz@ to Cc) Is C part of this patch still needs to be committed or can it be closed?
The C parts might be committed; the reason I hadn't done so is that the way is structured, there's a bunch of hardcoded offsets, and I'd need to take a really close look to make sure they match. And we don't really gain much by committing it - as the PR says, it's just leftovers that don't hurt.
