I somewhat doubt that you are remembering correctly. The POSIX standard
was published in 1988. I was starting to use Unix shortly before that
and I don't think there was really a common way to indicate the end of
the options. Some utilities used "-", some "--", some just stopped at
the first argument which didn't look like an option ...
The convergence to "--" happened later. My guess is that GNU getopt and
the popularity of the GNU utilities had a lot to do with it.

Right. But in this case lots of people were building different things
and then *one* of them was standardized. Truth to be told, I don't know
when that happened. It might have been in the original 1988 edition of
POSIX, but I don't think so. I think it was in a later (possibly much
later) edition, wennn "--" was already really common. But POSIX did lead
the way in some cases and it might have been the case here, too.
