to be used as a login shell inside tmux, so add a default-shell session option. This sets the shell invoked as a login shell when the default-command option is empty. The default option value is whichever of $SHELL, getpwuid(getuid())'s pw_shell or /bin/sh is valid first. Based on a diff from martynas@, changed by me to be a session option rather than a window option.
