It's useful for people maintaining older systems, so I looked
it up.  I confirmed it was introduced between 6.7 and 6.8.
Of the six copy.c-affecting commits in that range, only

I'll push this shortly:

   cp -u -p would fail to preserve one hard link for each up-to-date copy
   of a src-hard-linked name in the destination tree.  I.e., if s/a and s/b
   are hard-linked and dst/s/a is up to date, "cp -up s dst" would copy s/b
