(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 http://www.tldp.org/LDP/abs/html/internalvariables.html#IFSH .
