Edit filter configuration

Requested by [[User:Toddst1]]. Warn users adding unreferenced entries to day-of-the-year pages, per [[WP:DOYCITE]]? --Suffusion of Yellow 22:07 6 Mar 2021

Exclude pages like [[January 1970]] (different citing rules) as well as odd redirects like [[February 30]] --Suffusion of Yellow 20:32 7 Mar 2021

Changes to reduce FPs: Exclude bots, edits that add a template, and edits that touch existing lines and don't add a four-digit number. --Suffusion of Yellow 23:49 28 Jan 2022

Exclude reverts. --Suffusion of Yellow 23:54 28 Jan 2022

Update per FPs; don't match if adding a four-digit number to an existing line. --Suffusion of Yellow 21:34 7 Mar 2022

Set to warn, no objections at [[Special:PermaLink/1079184771#Set filter 1129 to warn?]]. --Suffusion of Yellow 19:29 25 Mar 2022
