From 3a3f6f0ab517109a60c0c1f8c08ae9b003c52a10 Mon Sep 17 00:00:00 2001 From: Austin Clements Date: Sun, 20 Nov 2011 20:00:55 -0500 Subject: [PATCH] emacs: Don't record undo information for search or show buffers. There's no reason to record undo information for read-only, programmatically-constructed buffers. The undo list just chews up memory keeping track of our calls to insert. --- emacs/notmuch-show.el | 2 ++ emacs/notmuch.el | 2 ++ 2 files changed, 4 insertions(+) diff --git a/emacs/notmuch-show.el b/emacs/notmuch-show.el index a7f32631..7be88f82 100644 --- a/emacs/notmuch-show.el +++ b/emacs/notmuch-show.el @@ -843,6 +843,8 @@ buffer."
