Cleaner?  Like I said, the baseline behavior should be what happens when
all the options are unset.  The cleanest output is none at all.

There's nothing that requires us to use NOUNSET in the code.  You yourself
used EXECOPT instead of EXEC, for example (and for obvious reasons).

} It does.

"setopt nohup" parallels it, but the output of "setopt" doesn't say "nohup".

} True, that's how the options used to work, but what is the "expected
} behaviour"?  It varies depending on whether we're emulating sh, ksh,
} csh, zsh, (when we get round to it) POSIX, or whatever.

The "expected behavior" is what you get when you run "./zsh" out of
the build directory on a machine that's never had zsh near it before.

Emulations are just that; they're by definition not baseline behavior
(unless what you're writing is nothing more than an emulator).

] Not to mention
} that not even all the non-special options defaulted to off anyway

The only ones that didn't are FUNCTION_ARGZERO, which is new; BG_NICE,
which has always annoyed me anyway (and which originally didn't default
that way, if I recall correctly); and the three HASH options, which
don't change any user-visible behavior, only performance tradeoffs.
