Change of behavior of shift+<numpad arrow keys> (without numlock)

Bugzilla 558 requests to change the behavoir of shift+<numpad arrow keys>

> In reasonable X GUIs (GNome/KDE), shift + <regular arrow key> selects text. 
> But if i press shift + <numpad arrow key>, i get numbers!  So the current XKB 
> behavior makes Shift kind of like the "lockless" version of Numlock, which is

This requests sounds reasonable so I would like to find out if
somebody has a strong opinion on this issue. 
If not I will commit the supplied fix.
