From 964709e115126aafa6fd5d8c984d511cf68cecaf Mon Sep 17 00:00:00 2001 From: Gabriel Schneider Date: Tue, 29 Sep 2026 02:17:14 -0300 Subject: Undo and Redo with nothing left say so, and the write succeeds A pane's Undo or Redo with no step left did nothing and said nothing. It now says "Undo: nothing to undo" (or Redo's) as a message, not a failure, so a ctl write of it still succeeds as acme's silent Undo does. The docs give the 256-step history.
