Эсхатология и герменевтика парапрограммных объектов

To make `mc` really open LibreOffice file (odt) for editing in Kubuntu 22.04, I had to purge the `wslu` package which seems to be installed by the default installer — Iʼve certainly not installed it intentionally.
mcʼs ext.sh calls `xdg-open` and stops if it reports success. `xdg-open` reported success although the called program `kde-open5` failed with WSL interaction. Somewhere in this chain, the failure fact was dropped.

Too tangled, as for my normal leisure.
