[Octave-bug-tracker] [bug #52169] gnuplot graphics toolkit tick color doesn't match axis color

[Dan Sebald]

Follow-up Comment #2, bug #52169 (project octave):

Since this is a regression, I've searched through all the patches I have here
(I always copy my patches to a local subdirectory before posting).  The
closest related patch (not sure it was ever pushed though) seems to be the
following from djs2017mar10

That date would be after the July 2016 timeframe.  Notice how the re is one
fprintf() removed that uses colorspec, but the one that is retained doesn't
have the color spec.  Again, not sure if this was ever applied, or exactly
what happened.  But this would be a good starting point for investigating
where the issue might be.

I'll look at this and come up with a changeset.
