• VSCode Version: 1.37.1
• OS Version: Linux x64 4.15.1-58-generic

Steps to Reproduce:

1. Remove trailing newlines from a file under version control.
2. Go to the Source Control view.
3. Try to stage the removal of these newlines: right-click on the right-hand side and select "stage selected changes"
4. Notice how there's still one removal that appears to have been left behind.
5. Repeat step 3
6. Now your removals have all been staged.

Expected behaviour: at step 3 the entire newline removal should be staged.
