How it works

git addprx 42

Adds pull request 42 as branch "pr/42" and rebases the changes against the current branch. What this means is that even if the pull request (of a bugfix was against master) it will now be rebased against the current branch (which could be the maintenance branch).

It also prints out a diffstat and all the commits with their new hashes at the end.
