... btw, I forgot to mention that I don't see any problem with
the patch's behavior for DEFAULT. What I see with both readline
and libedit is that if you type something reasonable, like
set timezone to d<TAB>
then it will correctly complete "efault ", without any extra
quotes. Now, if you're silly and do
set timezone to 'd<TAB>
then readline gives you "efault' " and libedit gives you nothing.
But I think that's your own, um, fault. We don't have any other
places where tab completion is so aggressive as to remove quotes
from a keyword.
