commitctx: treat `filesadded` more like `filesremoved`

Accumulating the filename in a list will have a negligible cost and deal with
the list of added files like the other ones will make is code cleaning simpler.
The two variable with very close name is not great, but my plan is to split most
of the code in a separated function which will make the "problem" go away by
itself.
