Does babel have an option to pretty-print the source map file itself?
When using the CLI to compile and create a sourcemap, as
babel --sourcemaps true --out-file compiled.js input.js, the
compiled.js.map file is one long line.
At present I manipulate the map manually afterward with
python -m json.tool < compiled.js.map > pretty.js.map, but it would be helpful if babel could do this directly.
