I used to think getopt needed a lot of changes, but I'm not so sure
anymore. getopt's current API works fine for me and I use it in all
my scripts. However,

I don't think that's necessary. In my own use, if I /know/ -a doesn't
have an argument (because I didn't specify as "a:"), then I never
check the optarg. And it's bad form for a flag to take an optional
argument; it either does or it doesn't and you know that in advance.
