+Subject: [PATCH] highlight & loop through urls in both directions
+
+Based on a previous patch (st-copyurl-20230406-211964d.diff).
+This patch fixes two bugs when looping forward:
+1. URLs on the same line iterated the same way as when looping backward
+ (right-to-left). Now it's left-to-right.
+2. When an URL in the first row was selected, looping forward didn't
+ work, it just got stuck there.
