SPECIAL NOTE ON EDITS MADE AT AROUND 23:29 ON 22 MARCH 2014: Due to a typo in the filter conditions, this filter today tagged several innocent edits. This was a mistake. Apologies for any confusion caused. -- User:AGK

Cleanp layout and reduce likely condition count.  -DF

Remove function to ignore if there is the text in old_wikitext. Callanecc 12 Sep 16

Change edit_diff_pst to added_lines_pst to avoid issue where the edit after the alert is picked up by the filter. Also removed size limit to cover more situations (such as when additional information is included in the same edit and for long sigs). Plus detect "confirmed" rather than "autoconfirmed" for manually confirmed users. Callanecc 19 Sep 16

Reverting Musik's change, the filter isn't working. Callanecc 28 Nov 17

Trying this again. This time I tested it to be working. ~MA

Suppress for subpages. -TC
