Correction to SQLGetData string length handling

Browse Source 
According to http://download.oracle.com/otn_hosted_doc/timesten/703/TimesTen-Documentation/ms.odbc.pdf and https://msdn.microsoft.com/en-us/library/ms710980(v=vs.85).aspx, the string length should not include the NULL character at the end.

Previous behavior would likely work without problems for any language that uses C-style null terminated strings, but adds a null character in the string when using the driver with a language that does not use C-style strings.
