Comment 19 for bug 1234725

It occurred to me that the bug we're seeing in the atached savegame and screenshots is not in the new code that I wrote, but in the calculation of the buildcap for the port space. The buildcap checks whether a portdock can be built nearby. This check makes sense, because a map editor might set some port spaces and then edit the shape of the water afterwards, or because another player has already conquered all the nearby portdock spaces. So, we should think very carefully before we change that code, because it has potential for new bugs.
