Range is set improperly for S3_copy_object_range

The end range for the following should be params->startByte + params->byteCount - 1.

Bytes in the middle are being written more than once and then it attempts to write one byte extra.

Lines 399 to 403 in 59b6237

	if (params->byteCount > 0) {
	headers_append(1, "x-amz-copy-source-range: bytes=%lld-%lld",
	(unsigned long long) params->startByte,
	(unsigned long long) (params->startByte + params->byteCount) );
	}
