Try the small test script in the message you are responding to.
It gives me:

        $ sh ./1.sh
        A= d e
        B= d  e

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.

Similarly for

	another=$(some command)

which is Ok not to dquote.
