Use 'set -u' in gettextized shell scripts
Originally created by @anonym on #9371 (Redmine)
So far we’ve been avoiding it, see e.g. this comment from
config/chroot_local-includes/usr/local/bin/tor-browser:
# Do not "set -u", else importing gettext.sh dies
# with "ZSH_VERSION: parameter not set".However, we can actually set -u as long as we set:
ZSH_VERSION="${ZSH_VERSION:-}"before sourcing gettext.sh in each such script (see git grep "\. gettext\.sh" for a list of candidates).
