We can use IFS is ls is really needed (for a command line option or
whatever) :

___________________________________________________________________________
theo@copernic$ touch "1 2 3" 12 13
theo@copernic$ for i in *; do ls "$i"; done
12
1 2 3
13
theo@copernic$ for i in  $(ls *); do ls "$i";done
12
ls: 1: No such file or directory
ls: 2: No such file or directory
ls: 3: No such file or directory
13
theo@copernic$ IFS=$'\n'; for i in  $(ls *); do ls "$i";done; unset IFS
12
1 2 3
13
___________________________________________________________________________


I'm not saying it's better to use ls though.
