Global gitignore file not processed

[rkimballn1]

Issue Type: Bug

This is a problem developing in WSL but probably exists elsewhere.
Using WSL Ubuntu:

1. create a global gitignore file following these instructions https://help.github.com/articles/ignoring-files/
2. Add a file to your repo, anything will do. Call it test.abc for example. If you do a git status command then this file you just added should show up as untracked.
3. Add this new untracked file to your .gitignore_global file. Now git status should not show the file. This verifies that you have successfully configured your .gitignore_global file.
4. Open your project in VSC and go to the source control panel. The file which is excluded in your .gitignore_global file will show up as untracked in this panel.

Because the .gitignore_global file is ignored by VSC I have over 3,000 untracked files in my source control panel.

Not sure why this was closed. The suggested stackoverflow answer is not related to my issue. My issue has to do with the GLOBAL gitignore file, not the .gitignore file. There is more than one gitignore file.
This is a bug, not a question.
Git is working correctly. This is not a problem with git. VS Code is not working correctly.
