[Rd] Mac OS 10 (not X11) failure to rotate symbols (PR#3602)

[Prof Brian Ripley]

This is not a bug: it is documented.  Please read what help(par) says
about rotation under crt.

I have already pointed this out to you (twice), as well as the fact that
there is no `R version 1.71' and that that port of R is now frozen.
