Just be aware that this one will treat *each* space character as a
separate delimiter.

unicorn:~$ mapfile -t -d ' ' arr < <(printf %s 'a *   ! d')
unicorn:~$ declare -p arr
declare -a arr=([0]="a" [1]="*" [2]="" [3]="" [4]="!" [5]="d")

This may or may not be what's wanted.  The version I used originally,
with read, treats each *group* of spaces as a single delimiter.
