If there's nothing at the path(s) cited in the "Legacy Software"
list, and a Spotlight search doesn't turn up any stray copies of
the TextWrangler app (e.g. on a connected drive), then the OS is
just deluded :-) and hasn't properly refreshed that list.
(PS: For reference, the "Legacy Software" list on my own
Catalina machine is quite inaccurate.)
