[Rd] Incorrect date range in austres example dataset?

[Andrew Janke]

Hi, R developers,

It seems there might be an issue with the "austres" example dataset in
the "datasets" package. The description in austres.Rd says it's
"measured quarterly from March 1971 to March 1994". But there are only
89 observations in the data as defined in the source code. By my count,
that only brings you up to about March 1993. Is there an issue with the
data transcription, or the Description?

I'm looking at the source code from the R 3.6.0 source distribution.

Cheers,
Andrew Janke
