I'm not talking about sorting the input; just the output.  E.g., instead of

    -ffoo -fbar -fquux -fbaz

being printed, we'd see

    -fbar -fbaz -ffoo -fquux

just to make it slightly easier for people who are visually grepping for
a particular option to see whether it's there or not.  The scanning of
options, and overriding previous ones, hasn't changed and isn't touched;
everything is determined well before the printing routine picks up.

(Or are you worried that people would see the output and become confused?
I can understand that, too.)

That was all before I found that code was already written to do a lot of
the work; I didn't want to reinvent the wheel just to add prettier spokes.
