    _______________________________________________________

Details:

With gnuplot 5.0.5, the following code plots a graph where with a duplicate
number of entries in the legend

a=linspace(1,10,100)
b=sin(a);
myerr=a*0+0.1
h1=errorbar(a,b,myerr)
legend("test");

if h1=plot(a,b) is used, there is just one entry in the legend, as it should.

This problem was not present for octave 4.0.2, and only appeared after
installation of octave 4.2.1 without any other changes.
OS: GNU/linux Slackware 14.2, 64 bit.
