Yes, you've said that in the past, and I think we agreed to disagree
on it.  My opinion is that it's a judgment call: sometimes duplication
is for the better, and sometimes for the worse.  In this case, the
original doc string of json-parse-buffer said almost nothing useful,
leaving almost everything to look up in another function's
documentation, which IME is annoying.  Referring to another doc string
is OK for some secondary details, or perhaps for some very complicated
issues.  Not for the main part of the doc.  Especially for a function
whose name doesn't necessarily speak volumes about its purpose.

Doesn't sound like something I'd say, not to that effect.  "Allowed",
yes; but not "required".  If anything, it is easier to refer to a
previous function in the manual, when two or more functions are
described one after another.  By contrast, doc strings are never
"near" one another.

I didn't like the original doc string, yes.  The manual I didn't
change, it was written that way to begin with.
