It has been my experience that fields surrounded by quotes are interpreted
as factors unless the stringsAsFactors switch has been set to false.  So it
seems the default behavior of read.table is to be clever.  Annoying as these
behaviors are, changing them would probably break existing code that expects
the function to execute the way it does.
