Why not? What was wrong with autoclosing ways to connecting ways?

Could the autoclosing issue some messages at the WARNING level, please?

By the way, I ran across to some Corine landuse imports that had split a 
polygon line because it contained so many nodes. I created a 
multipolygon out of that, with just the split lines in role=outer. I 
think that it is reasonable not to join connecting polygon lines, unless 
they are members in the same multipolygon.

I am looking forward to testing it.
