//[[User:Markhurd/hidetopcontrib.js]]
// Based on [[User:Ais523/hidetopcontrib.js]]

//            and continuing after any regex mismatch.
// 090615 MEH Cater for new <span class="mw-uctop">
//            Add userHideAllSubsequent user setting.
//            Fix issue reported by [[User talk:Markhurd/hidetopcontrib.js#Bug|Lenore]].
// 100407 MEH Use simplified regex that works on IE8.
// 100413 MEH Cater for new pages.
// 100428 MEH Cater better for new pages.
// 100519 User:Ale_jrb Cater for Single-Revision Deletion, newly available to Admins.
// 110520 User:Waldir Better page check.
// 120206 MEH Cater for IE renderer differences.
// 120207 MEH Cater for all skins.
// 120321 MEH Cater for [[Wikipedia:Added or removed characters|WP:AORC]] by removing support for top not using the mw-uctop class.
// 121123 User:Waldir Allow user configuration of link location and text.
// 150121 MEH Remove legacy Javascript.
// 170608 Fixed dependency declaration for mediawiki.util
// 180413 User:Amorymeltzer allow for compatibility with a couple other scripts present on contributions page
// 200107 User:Suffusion_of_Yellow use mw-contributions-title class instead of guessing which link is to the title

// This script hides lines according to who has the top contribution for a page.
// If userHideAllSubsequent=true, all subsequent contributions are hidden too, more like watchlists.
