Notes:
This seems to work to see section blanking, testing as log only to see if it gives false positives and for speed. OK, added basic check if the removed_text does contain "==", this line could maybe be made better by using a regex on it to check if it is "== sectiontitle ==" ..?? Reenabled, it still may give some false positives. --Beetstra Speedup, specificity --Beetstra bit upgrade? --Beetstra Small case tag, for consistency with other tags. -x null edit, small case change didn't get through - Cen trying to deactivate and reactivate - Cen tagged edits are not reassigned after rename, see bugzilla 18908 - Cen (added_lines == "") does not work, (length(added_lines) <<span class="ltr">1</span>) does .. curiously. Updating filter --Beetstra False positives on removing empty sections can we test for that? Crudely even old_wikitext contains [^=](==+) *\n\1[^=] (i.e. it had at least one empty section) might do the job. Rich Farmbrough. Encountered another form of blanking, attempted to add to filter --Beetstra Format. -DF
