What is the intent there? Did you want to pass this variable to indicator?

[kof]

Currently its not used at all

I believe it's just a left over

Well, if it is shouldn't we remove it? It is probably removed by many minifiers anyways.

[cubiq]

of course we should. I'll push it in the next commit. it causes no harm, not worth a release of its own :)
