The duplicates annoyed me as well; thanks for taking care of it.

However, there's something I'm missing here: why doesn't
list-colors-duplicates recognize grayNN and greyNN as duplicates?
We don't have them in the list that w32-default-color-map returns.

As for duplicates such as "Dark Slate Gray" and "Dark Slate Grey",
which are not filtered out because they _are_ in
w32-default-color-map, would something break if we modify the list
returned by that function to not include any duplicates in the first
place?
