__indexOf and coverage report

[genu]

Related to #2562

var __indexOf = [].indexOf || function(item) { for (var i = 0, l = this.length; i < l; i++) { if (i in this && this[i] === item) return i; } return -1; };

I realize that this is a workaround for lack of indexOf in IE < 9.0, however, coverage reports are affected since the .indexOf() is defined in most browsers.

Is there a way to disable IE less than 9 altogether to disable the extra indexOf definition?

I don't think there is a way currently, but this is one of the things that probably should be optional.

Perhaps, a workaround would be useful to avoid having incomplete coverage.

@genu As a another approach, you can try coffee-coverage. :)

Is it time to drop support for IE < 9?

2017 isn't 2010 anymore.

Fixed in #4526.
