bugfix: lib/util.sh: exceptions: log_e: must include `declare e` in the alias and not when save_e is called, so that $e is a local var of the caller. this bug did not appear in testing because the save_e alias, which re-scopes $e within log_e (), was not expanded inside log_e () (since new aliases were not loaded between save_e and log_e ()).
