It's in POSIX.2. My rewrite was an attempt to directly implement
the text of the standard. (I no longer have access to the standard,
unfortunately.) As you can tell from the code, the standard definition
is pretty unpleasant. There are places where it's not clear what state
is stored in parameters and what is supposed to be hidden, and the text
doesn't address the issue of multiple consecutive uses of getopts at all.
I wouldn't be surprised if there are actually bugs in the standard.
