//[[User:Markhurd/hidetopcontrib.js]]
// Based on [[User:Ais523/hidetopcontrib.js]]
// By a suggestion by [[User:Discospinster]]
// 090325 MEH Fixed where it is not hiding all (top)s, starting with redirects
//            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.
 
// 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.
