One could also argue that 2 out of 53 "no" options omitting the dash is
in fact broken, and a real reason to remove them.

I don't see the warning as "slapping wrists" so much as saying that
we're harmonizing our conventions and their scripts need to be updated
for the better.

That said, I'm not going to fight for this. My only goal here is to get
--wait and --no-wait added to pg_ctl.
