No patch was included in the distributed message. Moved to R-devel, as
this is not a help question.

This is not what is intended. R_ShowMessage should be showing messages
in a suitable way: for console-based systems that should probably be an
alert box. By not having R_ConsoleFile set R_WriteConsole is used.
I don't think you can assume that all users of that code will have a
stderr.

NO! That also redirects all the R warnings and errors to /dev/null, and
is definitely undesirable.
If you find the warnings (*not* errors) annoying, don't misuse R by
supplying incorrect arguments. Use e.g. environment variables to pass
your input.
