New description:
It would be really nice if this plotted an arrow from (1,2) to (3,4):
{{{
sage: v=vector([1,2])
sage: u=vector([2,2])
sage: plot(u,start=v)
}}}
or maybe the option should be "base" or "origin"
To fix this, just change the plot method in
{{{devel/sage/sage/modules/free_module_element.pyx}}}

Comment:
Okay, positive review on this nice addition from the original patch.
The reviewer patch still needs review; it fixes the problem by extending
the one-dimensional start as well, and adds/spruces up some documentation.
Reviewer should check things work, doctests, and that documentation looks
ok.
