From 238e35e89d387f3c266b40f107e9419ea75d77bb Mon Sep 17 00:00:00 2001 From: Gabriel Schneider Date: Mon, 28 Sep 2026 13:31:20 -0300 Subject: Joincol with no column to the right and Theme with no such theme say so Both did nothing without a word, from a click or a ctl write alike, and a script could not tell a no-op from success. Joincol in the rightmost column now fails 'Joincol: no column to the right'. A Theme name that is none says so and names the themes sharing its first letter, since all of them (ThemeSel lists them) are too many for a message or a refused write; a startup config line still fails quietly, as its other bad lines do.
