Options passed on the command line (as in an alias) override any others. I 
assume a function would be equivalent to an alias here, but I haven't 
checked as I don't use them.

There used to be debates on the efficiency of alias versus function, but if 
they're only taking nanoseconds to execute, what does it matter?
