#553 plot with linestyle doesn't work

[Jocke]

The following command should produce 3 asterisks at x = 1, 2, 3 but adds a line between the dots and hides the first asterisk

plot([1 2 3],[1 1 1],'*','linestyle','none')

it worked in 4.0

A dirty fix (to avoid the unwanted line) is to plot one point at a time with the "hold on" statement.
