23.0.60; Error in xterm-mouse-event

[Leo]

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:

I am getting the following error all the time. The steps to reproduce
this bug is as follows:

     i.   using putty in WinXP to ssh to Fedora GNU/Linux
     ii.  run emacs in it
     iii. enable xterm-mouse-mode and mouse-wheel-mode
     iv.  use the mouse to scroll down in putty

It works fine for me in an xterm.
That seems to point to the fact that putty does imitate xterm well
enough (surprise, surprise, nothing really does).

    That seems to point to the fact that putty does imitate xterm well
    enough (surprise, surprise, nothing really does).

That may be true, but it would still be good to make Emacs
work with putty as well as with xterm.
