    _______________________________________________________

Details:

This is a regression of the official Windows release, concerning the gnuplot
graphics_toolkit. 

The following code works fine in the Octave 4.0.2 Windows release, but it
works wrong in the current 4.0.3 Windows release:


clear, close all;
graphics_toolkit gnuplot

plot(1:10)
text(1,8, 'red text line', 'Color','r');
text(1,6, 'red text line with subscript a_b', 'Color','r');


My observation: With the Octave 4.0.3 Windows release, the second line is
plotted in black, and not in red. (Observed on two different Win7 machines.
Using the official Windows installer from the Octave website.)

If you skip the subscript part in the second text line, then this line also
turns properly red in Octave 4.0.3 Windows. Any other "latex interpeter"
command is also sufficient to trigger this bug.

This bug does not show up on my (self compiled) Octave 4.0.3 release on Ubuntu
linux.
