Only one trace appears in gnuplot

I have just compiled and installed octave-2.0.14 on a Redhat 6.0 system.
I've encountered a small glitch in plotting two traces on the same
figure.  It appears that the problem occurs when gnuplot is only sent a small
amount of data.

If I execute 

octave:1> a=[0:.1:5];
octave:2> plot(a,sin(a),a,cos(a))

gnuplot only displays the sine curve, whereas

octave:1> a=[0:.1:6];
octave:2> plot(a,sin(a),a,cos(a))

displays both the sine and the cosine curve.

Similarly, executing

octave:11> a=[0:.1:2];
octave:12> plot(a,sin(a),a,cos(a),a,(sin(a)).^2)

displays 3 traces, whereas

octave:9> a=[0:.1:1];
octave:10> plot(a,sin(a),a,cos(a),a,(sin(a)).^2)

only displays one trace.  However, adding an explicit data point of (0,0)
at the end

octave:15> plot(a,sin(a),a,cos(a),a,(sin(a)).^2,0,0)

then causes all three traces to display.

Is this a known problem?  Do others see this problem?
