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

NO! That also redirects all the R warnings and errors to /dev/null, and
is definitely undesirable.
