Non-root install of Wordpress in an already running nginx site

[Ian M. Evans]

Been running nginx on our server for years. php-fpm, multiple location
sections, etc., all working fine.

However, for one project we're launching my partner wants to run a
wordpress blog from a subdirecory, i.e., example.com/ournewblog

Can anyone point me to an example of a location block for the wordpress
blog that handles all the wordpress needs while not futzing with all the
other locations or causing php problems elsewhere?

Thanks!
