The idea is to just call it as many times as you want to.
It just sets an internal index that indicates which moved-to-path to use
for descriptions and resolution from now on.

You cannot 'remove' the path. Currently, if a move is detected we force
the user to choose a move target. Perhaps the API should account for the
possibility where the user decides that this is not a move after all?
With the current API you could work around this limitation by discarding
the conflict object, then get a new one and do not call get_details() on it.
This new conflict will offer the "accept/ignore deletion" options only.
But that's not very pretty.
