Update can't replace missing?

If I "svn up" into a working copy where something has been replaced by
an object of the wrong type (a file instead of a directory, or vice
versa), I get no error message from 1.5.2 (I do, from 1.4.4). Further,
the WC seems to decide I like things that way: if I remove the
obstruction and update again, I get nothing!

Is this a bug? Or am I just misunderstanding something, perhaps
related to the new --depth magic?

I get the behavior I expect out of: svn, version 1.4.4 (r25188) (OS X
Leopard version)

I get the surprising behavior out of: svn, version 1.5.2 (r32768) (I
think this is the CollabNet download)

Script attached demonstrates.
