octave 3.0.4 rc5

[Marco Caliari]

Dear maintainers,

I reported, against 3.0.4-rc1, the following two bugs

octave:1> x=linspace(0,1);
octave:2> plot(x,x,x,x.^2)
octave:3> xlabel('x')
octave:4> ylabel('y')
error: __go_draw_axes__: unknown object class, root figure

and reversed legends for

octave:1> x=linspace(0,1);
octave:2> plot(x,x,x,x.^2)
octave:3> legend('linear','quadratic')

which were not present in 3.0.3 and are still present in 3.0.4-rc5. I can 
solve them with the following quite trivial patches

I understood that (only) regressions should be fixed, according to the 
current policy, and I agree with it. Otherwise, I apologize for reporting 
these bugs twice.

Best regards,
