clientwin_property_change_hook, enumerate.lua

Hi,

i'm trying to implement some application specific window handling. What i
want to do is to get notified when a window's title changes and raise it. I
used to do this by hacking the C-code and catching a change to the WM_NAME
property, but i thought using a hook would be more elegent.

It turns out that my hook never gets called back. I copied the code from the
enumerate.lua script, and this also does not work as expected (if a window
title changes, the numbering is not updated).

Other hooks work fine with the same code, so i wonder if there is anything
else i need to do to get notified about property changes.

Version is 20080103.

Thanks,

Felix.
