Comment (by cypherpunks):

 This certainly isn't shell ninja code, but just adding something like

 # Make sure this script wasn't started as 'sh start-tor-browser' or
 similar.
 if [ "x$BASH" = "x" ]; then
         echo "The $complain_dialog_title should be started as './start-
 tor-browser'"
         echo "Exiting." >&2
         exit 1;
 fi

 would alredy prevent people from trying to run start-tor-browser using a
 shell other than bash.
 But this would be enough, as starting the browser using 'bash start-tor-
 browser' isn't a problem.
