This patch fixes a pesky bug that occurs when a file goes in to an error state (e.g. try to printf("\b") while in column zero (at least currently that causes stdout to go in to an error state)). Once in an error state all fprintf operations fail, if non-buffered there is no output, if buffered there is output. The fix is to report the result of the actual fprintf operation regardless of its current state.
