xterm-mouse-mode used to work under rxvt-unicode but does not any more.
I'm not sure who ist to blame (emacs or rxvt-unicode).

How to reproduce:

start emacs like so:

urxvt -e emacs-snapshot -Q -nw --eval '(progn (xterm-mouse-mode 1)(switch-to-buffer "*Messages*")(toggle-debug-on-error))'

then klick in the one window.  You'll see a backtrace etc.

I see:
- in *Messages*

Entering debugger...
[ is undefined
M is undefined
# is undefined
@ is undefined


- backtrace:
Debugger entered--Lisp error: (wrong-type-argument stringp nil)
  intern(nil)
  xterm-mouse--read-event-sequence-1000()
  xterm-mouse-event(nil)
  xterm-mouse-translate-1()
  xterm-mouse-translate(nil)


This happens with
rxvt-unicode (urxvt) v9.20 - released: 2014-04-26

IIUC you're saying it worked in 24.3 but it fails in 24.3.91, right
(the email subject seems to say that it fails in 24.3, but the commit
to which you bisected indicates the problem is new).

Yes, right, the version number in the subject is wrong.  I
actually tried to follow your advise from bug#17724 to use
24.3.9x in order to find bugs before the 24.4 release...

Thanks for looking into this, Gregor

Great, thanks, so yes I can reproduce the problem here.
It looks like rxvt-unicode uses yet some other escape sequences for
mouse clicks which are not documented (but somehow worked) in the code.

No, it was just a dump error on my part in the last change.
I installed the patch below which fixes it.  Sorry, and thanks for
reporting it.
