Color for plus symbol always black

I recently upgraded to the binary for Windows version 0.60.2
and found that the plus (+) symbol always plots in black even though a color is
specified. My fix was to change the parameter lines.markeredgecolor to
the color I wanted using the rc() command and then to revert to the default
using rcdefaults(). This works ok for me but I thought you might want to
know in case it’s a bug.
