(As people already pointed out in case the input is coming from a file
you should use a redirect.)

What you see has to do with the internal field separator (IFS), which is
usually set to space, tab and newline. Each of these characters is
considered a field separator i.e. a break point in your list. You can
read up on this at

Leonard.
