Rhino version does not create source map file

[SomMeri]

This is related to #2043. I used command:

java -jar js.jar -f less-rhino-1.7.0.js lessc-rhino-1.7.0.js --source-map less.less less.css

This is how less.less looks like:

.test {
  demo: value;
}

Source map file was not created.

Note 1: The --source-map option is not ignored by rhino, because following:

java -jar js.jar -f less-rhino-1.7.0.js lessc-rhino-1.7.0.js --source-map less.less

returns expected error:

output: undefined
the sourcemap option only has an optional filename if the css filename is given

Note 2: the same file compiled under node.js generated source map file:

{"version":3,"file":"less.css","sources":["less.less"],"names":[],"mappings":"AAAA;EACE,WAAA"}

Totally I got my map file by using this command:

java -jar js.jar -f less-rhino-1.7.0.js lessc-rhino-1.7.0.js --source-map --source-map-output-map-file=app.css.map app.less app.css
