Nikolai Kosjar 4b3a987c39 C++: Equalize startOfOperator() 
There are two versions of startOfOperator:
    * InternalCppCompletionAssistProcessor::startOfOperator
    * ClangCompletionAssistProcessor::startOfOperator

The latter started as a copy of the former, but the former got some bug
fixes in the meantime.  Adjust both versions to each other, so it's easy
to diff them and to extract the duplication in a follow-up change.
