cli/origin: Make utils function compute only the required data

And let the caller function do the actual display. This also makes the utility function compute only the required data to be displayed (the listing data is optionally displayed so compute on-demand).

This also renames the 'list' bool to 'with_listing'. 'list' is a python keyword (it's ok to reuse but editors usually color it differently than plain function names and that can be confusing).

Behavior conserved:
