I can't get lftp --no-empty-dirs mirror options to work. I'm running version 4.0.9

lftp -c "set xfer:log 1;
debug -o ${LOG} level ${ERROR_LEVEL};
open sftp://$USER:$PASS@${SERVER };
lcd $LCD;
cd $RCD;
set mirrorrder *.txt* *.bin* ';
mirror --verbose --no-empty-dirs --newer-than=${TOUCH_FILE} \
--include='[G|M][0-1][0-9]_(MGS_|GSP_|GSPO|VIB_|FAT_)[0-9]{12}\.ser' \
--include='[G|M][0-1][0-9]_(MGS_|GSP_|GSPO|VIB_|FAT_)[0-9]{12}\.sr2' \
--exclude ada/ \
--exclude bin/ \
--exclude temp/ \
--exclude files/hostaddr \
--exclude files/2002_archives ; bye;
