repl: improve doc for disabling REPL history on Windows
Environment variables with empty values are not permitted on Windows. As
such, to disable persistent REPL history one or more spaces should be
used. Node will trim whitespace from the variable, resulting in a blank
variable at runtime and the desired behaviour.
