If you care about your data in your variable and do not want
word-splitting at $IFS to happen, you should always dq your
variable.  A quick rule of thumb is that the only place that you
can get away by not quoting is straight assignment to another
variable, like so:

	var='a  b c '
        another=$var	;# another="$var" is fine but unnecessary.
