Details:

I'm using Octave 3.6.4 with Gnuplot 4.6 patchlevel 3 under Cygwin (Windows XP
SP 3). With the following code:

t = linspace(0, 2*pi, 50);
plot (t, [cos(t); sin(t)], ["xr;cos(t);"; "+g;sin(t);"]);

I obtain function plots with point style and colour as expected (red "x" /
green "+"). However, the legend label is "cos(t)" for both, rather than the
expected "cos(t)" for the red "x" / "sin(t)" for the green "+" plot. Only the
first label title is taken into account and is being repeated for the
remaining labels.
