From my test with gjslint v2.3.9, these two lines can be combined:

`gjslint --multiprocess --nojsdoc -r apps -r shared/js -e '$(shell cat ./build/lint-excluded-dirs.list)' -x '$(shell cat ./build/lint-excluded-files.list)'`

and the exclusion list can start with `apps/` or without; `gjslint` doesn't care. Also, it make sense to do `-r shared` instead of `-r shared/js` (if there are more JS being dropped into shared script in the future ...)

I can do this in another bug. Don't worry if you don't want to do it.
