I get:

gnuplot> set history -1
                      ^
          Unrecognized option.

Are you getting something else?  Of course, that means the following also errors:

gnuplot> set history +4
                      ^
          Unrecognized option.

Should we be recognizing the sign and then issuing an error if negative?

What should "history 0" do?  In the code, n=0 means print everything but that 
doesn't mean we can't issue an error.
