From c059b5eaa119e42de43b4fad3408b58f37a49147 Mon Sep 17 00:00:00 2001 From: Roland McGrath Date: Sat, 20 Nov 1993 01:41:51 +0000 Subject: [PATCH] (Frename_buffer): When the current buffer is already named NAME, don't short-circuit and just return unless UNIQUE is nil. This makes passing UNIQUE=t equivalent to (rename-buffer (generate-new-buffer-name NAME)). This is useful way to rename the buffer automatically so you can create another with the original name. --- src/buffer.c | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) diff --git a/src/buffer.c b/src/buffer.c index d0e1f9a3347..6b03e6d3e0c 100644 --- a/src/buffer.c +++ b/src/buffer.c @@ -560,7 +560,11 @@ This does not change the name of the visited file (if any).")
