Pushed with minor adjustments.  Notably, I didn't take your addition
of canonicalize_path() and referencing the file by absolute path.
That seems like an independent and rather debatable behavioral change.
All the other files that pg_resetwal touches are referenced with
relative paths; if we did want to change the reporting, shouldn't we
change it for all of them?
