number_pad:-1 qwertz keyboard

Reported almost exactly one year ago by a beta tester proofreading
the Guidebook, the number_pad setting to support the German keyboard
which swaps the Y and Z keys is for a keyboard that is used in other
places too.  The report mentioned France and Belgium; Wikipedia's
"keyboard layout" entry mentions "Germany, Austria, Switzerland and
other parts of Central Europe".  This changes references to "German
keyboard" (there were only a couple) into "QWERTZ keyboard".
