Check in file straight from hunk

[markosski]

Maybe this is already available and I just don't know it?

Here's my current workflow:

1. make code changes
2. start reviewing all local changes in hunk
3. git add <file> when file reviewed and no further changes needed
4. when all reviewed, push to branch
5. create PR

Would love to be able to do step 3 - git add <file> straight from hunk view.
