bug#5095: 23.1; emacsclient -t leaves terminal in an odd state if daemon not started

[Philip Armstrong]

If I start emacsclient like, without the emacs deamon already running:

$ emacsclient -t
or
$ emacsclient -t <filename>

and then press pagedown, emacs inserts the string "6~" into the buffer
at point.

If the emacs daemon has already started, or I use emacsclient -c to
open a new frame (-c) without the daemon being started, then pagedown
works just fine.

I've seen this bug both on emacs 23 in current Debian unstable, and
with one compiled from sources (ports) on OS X.

If there is no server present, you should get an error message like
this:

  emacsclient: can't find socket; have you started the server?
  To start the server in Emacs, type "M-x server-start".
  emacsclient: No socket or alternate editor.  Please use:

        --socket-name
        --server-file      (or environment variable EMACS_SERVER_FILE)
        --alternate-editor (or environment variable ALTERNATE_EDITOR)

Please provide a self-contained recipe for reproducing this bug.

I've set ALTERNATE_EDITOR to "", so emacsclient starts the server
automatically if it's not already running & then connects to it once
started.

bug#5095: 23.1; emacsclient -t leaves terminal in an odd state if daemon not started

[Chong Yidong]

Anyone have any idea about Bug#5095?  I can reproduce this:

emacs --daemon
emacsclient -t
[up]               =>     "M-o A is undefined"

Subsequent function keystrokes are handled correctly.

So it appears that the input-decode-map is not set up properly for the
very first keystroke on a terminal frame created by the daemon.  But
I've no clue why.

I've checked a fix for this bug into the repository.
