                  Status:                   Fixed => Confirmed

Follow-up Comment #15:

The original motivating code works with Matlab, but fails with the new
legend.m code.


x = 0:10;

plot(x, x+1)
legend('x+1');

hold on
plot(x, x+2);
hold off

legend('', 'x+2'); % first string is empty -> error


It should be possible to set an empty value for a legend string.
