Always no quotes for $() statement.
We don't need quotes to hold blanks in result:
# i=$(echo 1 2 3)
# echo $i
1 2 3
#
These quotes can make something wrong in some case:
# i=$(echo '!')
#
# i="$(echo '!')"
-bash: !: event not found
#
No real problem for current code in split.sh, only to use a
better code style.
