3# Ghostty sends TERM=xterm-ghostty, which ncurses doesn't know yet: without
4# its terminfo, less, htop, systemctl's pager and the like refuse to draw.
5# Installing the entry keeps truecolor and doesn't override what tmux sets.
6#
7# Bash gets the readline and shopt settings of this repo's devenv shell, for
8# interactive shells only (bash-completion is on by default in NixOS).
