Issue report: subversion 1.7.2 windows command line client cannot copy URL -> WC if URL contains externals

Hello, dev,

I've encountered an issue with *svn copy* command.
I report it here because I did not find a way to report in in the issue
tracker <http://subversion.tigris.org/issues/reports.cgi>.
It cannot copy a directory by its url to local working copy if the
directory contains valid svn:external property.
Instead of correct copying, it shows error like this:

*svn: E720005: Can't move* 'C:\t\wc\.svn\tmp\svn-8ED6923C' to
'C:\t\wc\externals-container-copy': *Access is denied.*

The *repro.bat* composed according to
recommendations<http://subversion.apache.org/docs/community-guide/issues.html>is
attached (please rename it to repro.bat).

*operating systems* where I tested:

*Windows 7 Professional* x86-32bit SP1 Microsoft Windows [Version 6.1.7601]
*Windows Server 2008 R2* Standard x64-64bit SP1 Standard Microsoft Windows
[Version 6.1.7601]

*svn versions* where I tested:

svn, version *1.7.2* (r1207936)
   compiled Nov 30 2011, 02:05:23

svn, version *1.7.1* (r1186859)
   compiled Oct 28 2011, 13:40:58

Additionaly, this makes
svncopy.pl<http://svn.apache.org/repos/asf/subversion/trunk/contrib/client-side/svncopy>contribution
script fail on this error.

Full output of repro.bat:
