For "override" read "add to". But if you put them in the other order,
for "override" read "override". :-)
In other words, if you specify the same option twice, you can't (without
looking at the code) know how the options are going to interact with
each other. It ought be be better (maybe even forbidden to use -q twice)
but as more and more options have been added, the code has become rather
messy.
