Hello,

There is a serious bug in 1.6.6 (and in 1.6.5), external directory is
not deleted when svn:externals property is deleted.

That means that subsequent updates from a certain revision without any
modifications made to the target working copy will fail:

svn up -rN   (svn:external set to "URL ext")

svn up -rN+1 (svn:external deleted)

svn up -rN+2 ("ext" directory added) - will fail because "ext" has not
been deleted!


Attached script reproduces the problem.
