bug#811: 23.0.60; emacsclient -t inserts one char when pressing an arrow key

[Tassilo Horn]

Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the emacs-pretest-bug@gnu.org mailing list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

1. Start emacs -Q
2. eval (server-start)
3. from a terminal, invoke emacsclient -t some-file
4. Press <left>, <right>, <up> or <down>

The first keypress of an arrow key after the emacsclient invokation
inserts one D, C, A or B.  The next press moves point as expected.  With
emacsclient -c this does not happen.

If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
If you would like to further debug the crash, please read the file
/usr/share/emacs/23.0.60/etc/DEBUG for instructions.

Thanks.  I can reproduce this too.  Do you know whether or not this
problem only appeared recently?

No, sorry.  Normally I use emacsclient -c all the time.  But since
nobody has reported it before, I'd say the problematic change shouldn't
be too old.

Bye,

bug#811: 23.0.60; emacsclient -t inserts one char when pressing an arrow key

[Chong Yidong]

Anyone have any idea what causes this bug?  I noticed that if you switch
to the X frame, then switch back to the terminal frame, the first arrow
key you enter into the terminal then behaves correctly.  Very strange.

I've checked in a fix.
