I don't see this with the current Octave sources or 3.2.0.  I'm using
gnuplot 4.2 patchlevel 5 on a Debian testing system.

As I recall, mixing line styles and colors has never really worked
correctly in gnuplot and the behavior is terminal dependent.  But
maybe things have changed lately?  I'm not sure.

Did you use -depsc or -deps?
