// TYMCZASOWA ZASLEPKA. Modul scalania koncow (plan_join / join_ends) nie zostal nigdy
// zacommitowany: commit 4ddfeb02 dopisal `src/editor/join.cpp` do CMakeLists i `#include` w
// planpanel.cpp, ale samych plikow nie ma ani w drzewie, ani w historii, ani w stashach. Bez
// tego naglowka i join.cpp branch sie nie kompiluje wcale. Ta zaslepka odtwarza dokladnie to
// API, ktorego uzywa panel planu, i mowi "niedostepne" - zeby reszta edytora dala sie uruchomic.
// Do zastapienia prawdziwym rozwiazaniem geometrii (luk-prosta-luk) i chirurgia dokumentu.
