done

And you need to run make man/git-squash.{html,1} to regenerated the doc.

[elonderin]

done also that.

btw:

• shoundn't that step be mentioned in CONTRIBUTING.md ?

This requires a GitHub bot to commit the output into this repo or store it something. However we don't have the right/resource to do it yet.
