I wonder what users will think of these 
integer, uinteger, zuinteger-unlimited, etc. references.  I mean,
these are internal setting types, we don't describe them anywhere,
right?  Maybe the description here should be closer to the
manual description, telling users to loop at the documentation
of each setting to know which values to use.

"for zuinteger-unlimited settings", I suppose.  Same thing
appears in other places below.

Otherwise LGTM.
