reasons:

• no more duplicate nodes error in that area (even fixed 2 of the 3 minor warnings left there)
• used both measurement plugin and validator on serveral other objects with JOSM revision 1089 (latest to date)

@reporter: please check with latest revision since 746 should really be obsolete now
