Changeset 10385 for sites/trunk/wordpress.org/public_html/wp-content/mu-plugins/pub/wporg-redirects.php

Timestamp:

Message:

Open-source a bunch of redirects that were in sunrise.php (and a handful of similarly related redirects that didn't exist).

This will hopefully allow simpler recording of some of the generic redirects that are active, and may allow others to easier add/patch them.

See #5345.
