This isn't the same as ignoring it. Suppose we do
setDividerSize(5);
setDividerSize(-1);

what is the value after both of these - per your ignoring code 5, but per your 
doc it will be whatever the default was before you started to change it.

I think it sufficient to say it will be ignored and drop the 2nd clause.
