Let's not do special cases, that just makes Postfix more confusing.

To raj's concern about this making main.cf harder to understand,
I'd like to add that postconf would display only the final value:
main.cf:
# Assuming that foo has a default value of 'whatever'
foo += bar
foo += baz
Command and output:
$ postconf foo
whatever bar baz
People who must use "grep" would have to do some extra work.
