I don't remember exactly; ISTR there being a bunch of fencepost errors,
error handling errors, errors handling unusual cases and so on. The code
was so messy that it was easier to start from scratch -- most patches
to that code were introducing new errors while fixing the old ones.
Of course, getopts is a particularly bad design, so the code can't help
being messy to some extent.

Probably. I remember having some difficulty working out where optcind
should be reset -- it's all very implicit in the POSIX definition.
