xset/xterm: since update from 1.4 -> 1.5 not able to disable beeping via 'xset -b' or 'xset b off'

[O. Hartmann]

Since the X11-update from libraries and applications 1.4 -> 1.5 the 
xterminal keyboard beeping, disabled by 'xset -b' or 'xset b off' 
doesn't work. In xterm, I get beeping although I disabled beeping via 
the above mentioned xset command.
