Follow-up Comment #1:

I think this can be documented more clearly, but the behavior should probably
stay Matlab-compatible.

For the sample code, Matlab produces 10 line objects.  The "LineStyle"
property is '-' and the "Marker" property is 'none'.

Octave does nearly the same thing.  It creates 10 line objects with
"LineStyle" = '-'.  However, the "Marker" property is '.' which thus at least
displays the points.

Interestingly, I'm pretty sure this is a change in behavior for Matlab.  I
remember that Octave had to introduce a special case for one point like this


plot (0.5, 0.5)


so that the "Marker" property would be '.' rather than the default of "none". 
That it still the case.  This code


h = plot ([0 1], [0 1])
get (h, 'marker')


is not special-cased because it has more than one point and the "Marker" is
"none".
