The Open Changes button not displayed as disabled for files without any changes

[cateyes99]

VSCode Version: 1.12.1
OS Version: OS X EI Capitan 10.11.3

Steps to Reproduce:

1. Open some project from GitHub.
2. Open a file A.cs which has no fresh changes at all.
3. Stay on the editor of A.cs, and notice the button of Open Changes on the top right corner above the editor doesn't display as disbled! Clicking it has no effect of course, but it should display as disable in this case just like what in the old versions.

Can't fix without #21131, closing for now.

[cateyes99]

since it connot be fixed without #21131, should this be kept open and linked to #21131 then?

[joaomoreno]

Sure.

To keep the number of issues in our inbox on a manageable level, we're closing issues that have been on the backlog for a long time but haven't gained traction: We look at the number of votes the issue has received and the number of duplicates issues filed.

Thanks for your understanding. Happy coding!

Hoping to re-open this because I got this as a feedback item from a few CS educators. They notice their students clicking it accidentally and being confused when there is no apparent action.

I think this has regressed, I now miss this button when a file is staged.

Fixed regression with 3232379

There is another regression (#131739), so I will be reverting this fix for this, and will refactor it.
