The improved version of a grob description I showed neither uses a
definite nor an indefinite article for that.  I think it should be
clear that on a page that describes grob 'foo', the displayed default
value is for exactly this grob.  Don't you agree?

*If* we had a page that showed all grob properties, then we could do
that.  However, right now we repeat a property description for each
and every grob if it gets used.  Assuming a description page for grob
'foo' I see no additional value in having default values displayed for
other grobs; this just makes the description unnecessarily longer.

I'm left-handed by myself (but playing the piano), and I don't feel
offended :-) By the way, AFAIK you are the very first person that ever
mentioned this issue.
