When has this changed?  Or maybe there are still situations where an
anchor is needed, thus the example has to be improved?

The respective diff from 2.16 to 2.18 in scm/define-grobs.scm reads:

However, reverting all that does not appear to make a change (unless
I am doing something wrong here).  So I'm not sure what to attribute
the change to (the logs for lily/ or
lily/ do not show anything suspicious to me

Thanks for testing.

How important is it to figure out the responsible change?

Well, it's not important (at least not for me), but `anchors' was a
central concept in vertical positioning of grobs, and lo and behold,
it is no longer necessary, so we can correct the documentation.

Could have something to do with issue 3330, committed as part of
2.17.19.  No idea just _what_, though (but it streamlines and amends the
spacing engine considerably, so it would be a likely candidate).  Do we
have the docs for 2.17.18 and 2.17.19 for comparison?  In other words,
I'm a bit lazy.

Happened between 2.17.26 and 2.17.28
