Subject: 29.1; garbage inserted in the buffer when starting Emacs in xterm
Date: Wed, 17 Jan 2024 15:32:04 +0100

1. Create a large file "foo", e.g. with
     echo `seq 10000000` > foo

2. In an xterm, connect to the machine via ssh (AFAIK to introduce
   a delay in the transmissions).

3. Type (without <RET>):
     /usr/bin/emacs -nw -Q --eval="(setq large-file-warning-threshold
     100000000)" foo

4. Type <RET> twice very quickly.

I sometimes get garbage near the beginning of the buffer, after a
blank line (due to <RET>):

11;rgb:0000/0000/00001 2 3 4 5 6 7 8 [...]

I could reproduce this bug in Debian/stable (emacs-nox 1:28.2+1-15),
Debian/unstable (emacs-gtk 1:29.1+1-5), and Android with Termux
(GNU Emacs 29.1).

Without -Q, the bug occurs more easily: no need to be particularly
fast (I get it with <RET> to validate the command + <next> or <end>),
and the file may be smaller.
