Remove Unused `move_to_front_of_path` Function
Remove Unused `move_to_front_of_path` Function

In #440, a `move_to_front_of_path` function was introduced, but
was [ultimately not used][1] when these changes were merged as f7c73f7.
The function itself was not removed, however.

This commit removes the unused function.
