Yes, the xref navigation stack is exposed via Edit, Go To, Back/Forward,
so perhaps it can be extended to support tracking and going to previous
editing locations, if users enable an option.

Another question is how to track the edit locations efficiently.  A
naive implementation would be to add a function to
after-change-functions if the xref setting is enabled.
