Quick copy lines in diff view

[borekb]

When I'm comparing files before I commit them to Git, it would often be useful to quickly revert a hunk by clicking some small arrow like this (I'm not a designer):

I use a similar feature in Beyond Compare (note that in this example, both sides are editable hence the arrows work in both directions):

This is coming with #18615

@joaomoreno Any chance this could be reopened? I think this request is different from what was delivered #18615 (specifically, #18615 (comment)):

• Polish git as an SCM extension #18615 only works in the context of SCM, not in generic diffs ('Select for Compare' + 'Compare with ...')
• Clicking an arrow is a faster and more discoverable UI.

I also vote to reopen this.
