When "getNextBlock" was called after "getNextLine", the pointer could still on the newline.

The pointer to a newline could not advance enough, when the line ended with \r\n. The resulting buffer was correct, as the buffer range went from <start> until \r, but that the pointer increased by just 1 could lead to the problem that the next pointer points at \n, which is still part of the newline and therefore, "getNextBlock" got 1 byte too much.
