It's a bug in the original code, however I do have a question;

I think the option to "Include final label" is ambiguous.
In the case of "number of labels", if the number of labels is set to
10, and "include final label" is selected, should you end up with 10
labels or 11?
Would it be clearer to say "Add final label"?
In this case,
if "label interval" is selected, the behaviour would be unchanged (the
final label is added),
if "number of labels" is selected, then the label spacing would be
unaltered and an extra label would be added to the end (giving a total
of 11 labels).
