Be careful to not touch curses variables if cur_term is null Curses variables like `enter_italics_mode` are secretly defined to dereference through the `cur_term` variable. Be sure we do not read or write these curses variables if cur_term is NULL. See #8873, #8875. Add a regression test. 2022-04-16 13:25:38 -07:00			`#!/usr/bin/env python3`

color: prefer `set_color --reset` over `set_color normal` `set_color normal` is too ambiguous and easily misinterpreted since it actually reset all colors and modes instead of resetting just the foreground color as one without prior knowledge might expect.
