Suboptimal and suspicious patterns using COM macros and functions

Hey.

I was reading sources of TSVN (latest version) and stumbled upon two minor things:

1. In src\SubWCRev\Register.cpp and src\TortoiseShell\ItemIDList.cpp when checking HRESULT values the check is done like this: if( !SUCCEEDED( res ) ) {} . Instead FAILED macro could be used ( if ( FAILED( res ) ) {} ) - this would give exactly the same effect and more readable code.

2. In src\TortoiseShell\ItemIDList.cpp near the end of ItemIDList::toString() method there's a condition:
           if (szDisplayName == NULL)
        {
                CoTaskMemFree(szDisplayName);
                return ret; //to avoid a crash!
        }
The call to CoTaskMemFree() will have no effect if szDisplayName is NULL - this call only pollutes the code.

I suggest these minor code defects are refined.

Best wishes.
Dmitry.
