Should this work: (|(sn=hughes)) ?

["John Hughes" <john@Calva.COM>]

Maybe I'm misinterpreting things, but I'd expect:

	(sn=hughes)
	(&(sn=hughes))
	(|(sn=hughes))

to all give the same results.

But they don't, the "or" version returns no data,
and doesn't seem to do any search at all.

Running with -d36 I see:
