Interrupt or unclean shutdown: renamed files may stay not renamed back on remote side

Line 135 in b55a4aa

!sh ../etc/rename_files_pre.sh $DATAEXT $PREEXT || exit

repeat --until-ok -d $SYNCTIME put -E go && echo put_ok
rm go
!sh ../etc/rename_files_pre.sh $DATAEXT $PREEXT || exit
mput -c -E *$DATAEXT$PREEXT # interrupt here
 # files are left unrenamed and this file will be overridden by next 'go'
source rename_remote_norm.lftp
!rm rename_remote_norm.lftp

rename_files_pre.sh handles such case only if there are no new files with $DATAEXT

for f in *$1
do case $f in
    "*"*) # no DATAEXT files, list DATAEXT PREEXT prefixed, if any
        for f in *$1$2
        do  case $f in
            "*"*) exit 1;;
            *) echo "mv $f ${f%$2}";;
            esac
        done
        exit
    ;;
    *)  mv "$f" "$f$2"
        echo "mv $f$2 $f"
    ;;
    esac
done

Thus after any unclean shutdown empty/repair 'go' cycle must be done in first place.
