Need to add files: [] to tsproject and create baseconfig with compiler options to extend from

I have tried https://github.com/RyanCavanaugh/project-references-demo

and tsc -b tsproject.json emits the output files into the /lib directory as expected, but additionally generates (some of) these files again next to the *.ts source files which seems unexpected.

Example session:

> git status
On branch master
Your branch is up to date with 'origin/master'.
nothing to commit, working tree clean

> tsc --build tsproject.json

> git status
On branch master
Your branch is up to date with 'origin/master'.
Untracked files:
  (use "git add <file>..." to include in what will be committed)
        animals/animal.d.ts
        animals/animal.js
        animals/dog.d.ts
        animals/dog.js
        zoo/zoo.d.ts
        zoo/zoo.js
nothing added to commit but untracked files present (use "git add" to track)

Thanks for the patch!

Is it necessary for tsproject.json to inherit from tsconfig-base.json? If that config isn't directly controlling any files (due to files: []) it seems like compiler options are a moot point.
