fix failed write reporting by fwrite in line-buffered mode
when a write error occurred while flushing output due to a newline, fwrite falsely reported all bytes up to and including the newline as successfully written. in general, due to buffering such "spurious success" returns are acceptable for stdio; however for line-buffered mode it was subtly wrong. errors were still visible via ferror() or as a short-write return if there was more data past the newline that should have been written, but since the contract for line-buffered mode is that everything up through the newline be written out immediately, a discrepency was observable in the actual file contents.
