"mysqldump --extended-insert" could insert linebreaks between rows

Currently, mysqldump --extended-insert outputs all rows on a single line, which makes it difficult to use with various Unix command-line utilities such as grep and diff. If mysqldump could emit a linebreak between each row, that would make it easier to work with, without significantly affecting dump or restore performance, or affecting compatibility.
