The spacing is to print all elements in the same field width, and 10
wouldn't look good in a field of with 2. I don't think that could be
much different (compare 1:100 and 1:99). The labels would seem to be
generated to make room for the label with the longest possible width,
which is slightly botched since that width need not be used by any of
the labels. Submit a patch?
