[PATCH 9/9] config: run setup before commiting pager choice

[Jonathan Nieder <jrnieder@gmail.com>]

From: Nguyễn Thái Ngọc Duy <pclouds@gmail.com>

For the pager choice (and the choice to paginate in the first place)
to reflect the current repository configuration, the repository
needs to be searched for first.

That’s the end of the mini-series.  I hope you enjoyed reading it as
much as I did adapting it.

Looking forward to your thoughts,
Jonathan
