gh stack rebase --no-trunk: Reviewer-friendly rebasing for stacked PRs

TL;DR: gh stack rebase --no-trunk is a reviewer friendly way to rebase your stacked PRs. Just as the blog title suggests.

Regarding GitHub stacked PRs: If you’ve already got someone reviewing a PR and they’ve requested changes, the temptation is to just do gh stack rebase to get all your stacks updated again. Out of the box this has the side-effect of pulling an updated dev and rebasing the first branch on it.

That leaves the reviewer with a completely new set of commits and there’s no way to view just the changes since the last one.

To work around this, you can use gh stack rebase --no-trunk - this rebases just your branches on top of one another - you don’t pull in dev and the reviewer has an easier time reviewing the PR. Be kind to reviewers!
