Comment (by ncohen):

 > 2: There is no index where to add... So, more work to poset
 documentation project.

 Oh, no index for lattices. Right, sorry for my remark !

 > As of 1, I did not do that for now; this is direct copy from
 `join_`-counterparts. Point 4 is done, but long line of `==` is still
 quite hard to read.

 As you wish. Remember that there is some time there to save if you have
 time problems later on.

 > Also this same time I removed totally unused argument from
 `cover_relations`. Is this OK to do in ticket title saying nothing about
 it?

 I don't mind. It will depend on the reviewers, though.

 I will run all tests on a machine to check that removing this keyword does
 not break anything somewhere.
