Included is a patch to change the behavior when legend() is called with
numpoints less than or equal to 0. Currently if one makes such a call, some
cryptic error messages are printed out and the plot is not generated.
The included patch produces a warning, and defaults to using numpoints = 4, so
the plot is actually made.
