Agreed.

I ran into at least 2 different implementations of *get_origin.  There
is lv_origin_dup() and _origin_disp.  Both utilize the same logic with
slightly different output.  I haven't looked around it see if there are
others.

To clean this up correctly I would want to write what you are suggesting
and then use it in all the different places.

There is quite a bit of code that could certainly benefit from
decoupling the generation/manipulation of the data from the presentation
of it.

I've added this to a todo list.
