	garbage inserted at the beginning of the buffer when starting Emacs
	in a terminal on a remote machine
Date: Fri, 30 Mar 2012 03:20:44 +0200

Start "emacs -Q" on a remote machine with a slow connection, well...
a high latency (e.g. ADSL during a file transfer). This is not always
reproducible, but I sometimes get something like:

;; This buffer is for notes you don't want to save, and for Lisp evaluation.    
;; If you want to create a file, visit that file with C-x C-f,                  
;; then enter the text in that file's own buffer.                               

0;276;0c

Moreover the first three lines are entirely red, instead of white
(and red only for the semi-colons).

I already reported the problem in the past:

  http://comments.gmane.org/gmane.emacs.bugs/16480

and it is still not fixed.

Actually Emacs should be run in an xterm (after connecting to a
remote machine by ssh).

It's a known problem.  You can work around it by setting
xterm-extra-capabilities to t or nil.

How?

Adding

(setq xterm-extra-capabilities t)

at the beginning of my .emacs doesn't change anything (of course,
I run "emacs" without the -Q argument, so that my .emacs is run).

Did you test it with Emacs-23 or Emacs-24?  It's new in Emacs-24, so
it's no surprise if it doesn't solve your problem in Emacs-23.

`t' is an undocumented setting for xterm-extra-capabilities.
(Also, the doc-string has an incomplete first line.)
Also, sounds like there should be a PROBLEM (and/or NEWS) entry
about this.
