So, is it Ok to use current `SetValueFromCString` api from ValueObject to ask 
synthetic provider to update the underlying string?
You mentioned previously that we may add `SetSummaryFromCString` api - in fact 
currently this is what I am doing - changing the whole string through its 
summary (please check attached gif for example).
But the problem with the new API is the same as for the changing characters 
through `SBValue::GetData` - IDE doesn't support it
