preparing to push input validation rework for quiver and quiver3.  noticed
that while arrowheads turn off for any linestyle with a marker specified, they
turn back on if you also supply a name-value pair line style.  in matlab
2023a, the arrowhead stays off. e.g.:

h = quiver (0, 1, 2, 3, "-o")

has a marker with no arrowhead.  

h = quiver (0, 1, 2, 3, "-o", "linewidth", 10)

the arrow body width is increased to 10, the marker stays, but the arrowheads
reappeared. 

after pushing the other changes along with a xfail BIST for this case, will
look to see if its an easy fix.
