Why using afxDump now in VS2013 generates extra TRACE output

Question

Hi,
since using VS2013 instead of VS2010 old code using the afxDump object creates "extra" output.
Something like:
d:\...\bcgcbpro\bcgcbpro.cpp(39) : atlTraceGeneral - BCGCBPRO.DLL Initializing!
The reason for the TRACE related output is to be found in "dumpcont.cpp":
void CDumpContext::OutputString(LPCTSTR lpsz)
// use C-runtime/OutputDebugString when m_pFile is NULL
if (m_pFile == NULL)
TRACE(atlTraceGeneral, 0, _T("%s"), lpsz);
return;
ASSERT( lpsz != NULL );
if( lpsz == NULL )
AfxThrowUserException();
// otherwise, write the string to the file
m_pFile->Write(lpsz, static_cast<UINT>(_tcslen(lpsz))*sizeof(TCHAR));
One of the most unreadable outputs via afxDump is:

Is there any chance to switch the TRACE output off?
Since the big changes in the ATL library and since the AtlTraceTool got unnecessary removed from the distribution ... how to configure TRACE output?

Hello Together,
I have got this issue now in porting Sources from VS2010 (vc10) to VS2013 (vc12)
The recommended fixes in 
https://social.msdn.microsoft.com/Forums/en-US/cfc569ef-e229-4559-b245-ece2bba1e238/getting-rid-of-atltracegeneral-category-shown-in-atltrace-output?forum=vcgeneral
defining ATLTRACE and ATLTRACE2 with own Custom Methods worked fine for me. All
simple TRACE - calls  but only in my own code was handled better.
But afxDump - Output is not affected by this change. 
After some investigation I believe the here suggested tip
ATL::CTrace::SetLevel(ATL::CTrace::DisableTracing);
will also not produce the expected results, because it will simply disable all the afxDump-Output. by returning the method.
I believe, Microsoft has to implement some flags to configure and suppress filename/category-Output for afxDump (CDumpContext), and finally in _CrtDbgReportW because CTrace::TraceV will finally run in
this method. So, the output of 3rd-party assemblies could also be affected. (probably also for ATLTRACE, ATLTRACE2 to avoid own override of TraceImplementation.
In this case I will see dump output, but without filename/category
eg. 
#ifdef _DEBUG
afxDump << "ValidateName: returns <" << fileName << "> \n";
#endif
should return simple (old) output
ValidateName: returns<SomeTestFileName> 
instead of funny:
f:\dd\vctools\vc7libs\ship\atlmfc\src\mfc\dumpcont.cpp(23) : atlTraceGeneral -
ValidateName: returns <f:\dd\vctools\vc7libs\ship\atlmfc\src\mfc\dumpcont.cpp(23) : atlTraceGeneral -SomeTestFileNamef:\dd\vctools\vc7libs\ship\atlmfc\src\mfc\dumpcont.cpp(23) : atlTraceGeneral

I think, I will replace some of these simple afxDumps with simple TRACE with pre-formatted-single string.
