Can't stage empty removed last line

[usernamehw]

Issue Type: Bug

1. Remove an empty line from the end of the document
2. Select all text Ctrl+A
3. Git: Stage Selected Ranges
4. The change is not staged

If you remove a text before that last line and try - it will stage everything but the last line.
