legend and textposition

[pantxo diribarne]

Hi,

I noticed that setting a legend "textposition" property redefines the entire legend. For example : 
octave-3.6.1:2> plot(1:10)
octave-3.6.1:3> h = legend ("toto");
octave-3.6.1:4> set (h, "textposition", "right") ## changes textposition 
octave-3.6.1:5> set (h, "textposition", "left")
==> error: set: invalid handle (= -7.3835)

Is it an expected behaviour?
