Both of you are wrong ;-)
Of course, the lack of dq around echo's argument makes shell split
two and spaces into two args and feed them separately to echo, and
causes echo to show them with a single SP in between. Peff's
exampel should have been
BAR=$FOO sh -c 'echo "$BAR"'
But that does not have much to do with the primary point Peff was
talking about, which is that in this sequence:
$ x="two spaces"
$ y="$x"
$ z=$x
$ echo "x=<$x>" "y=<$y>" "z=<$z>"
assignment to y and z behave identically, i.e. dq around "$x" when
assigning to y is not needed.
