bug#6685: 23.2; Discards control characters during boot.


From: Andrew Hyatt
Subject: bug#6685: 23.2; Discards control characters during boot.
Date: Thu, 08 Sep 2016 01:08:55 -0400
User-agent: Gnus/5.13 (Gnus v5.13) Emacs/25.1.50 (darwin)

I was trying to reproduce this in Emacs 25, but emacsclient will not
start up a new emacs instance with emacsclient. According to the
documentation I have on emacsclient on using the alternative editor
flag:

If the value of EDITOR is the empty string, run "emacs --daemon" to
start Emacs in daemon mode, and try to connect to it.

So I can't reproduce this issue anymore.  Let me know if I'm missing
something, please.
