lost properties when moving added files

Hi,

When moving added (but not yet committed) files, the properties already
set on such files are lost:

$ svn co http://server/svn/testrepo/trunk testwc
$ cd testwc
$ echo test > test.cpp
$ svn add test.cpp
$ svn propset svn:mime-type text/cpp test.cpp
$ svn proplist test.cpp
  svn:mime-type
$ svn mv test.cpp test2.cpp
$ svn proplist test2.cpp
  svn:mergeinfo

As you can see, the renamed/moved file gains an svn:mergeinfo property,
but looses the svn:mime-type property.

All this with the latest release version (1.5.3).

It works ok with the latest build from trunk though.

Stefan
