Finally! I've found out how to make multipolygons!

heh! I didn't bother learning how to do it for a long time. Relatively recently I discovered that the JOSM 'multipolygon' menu option does everything for you if you select the outer way and the inner "island". Easy!
So I do use it now occasionally, but mostly these, like many relations, are fiddly bit of intricate complexity which we could do without.

I tell you, this horse track is a work of art.
