Aaron Griffith a2b1f238d9 changed markers.js to output one marker per line
this has been requested *many* times, because it makes it easier to
(1) learn what format markers.js uses, and
(2) write shell scripts that process markers.js.

It shouldn't break existing processors that use json loaders, and does
not drastically increase file size (just one extra byte per ~70).
