Problem: rfc822.py in 1.5.2 final loses the quotes around
quoted local-part names.

The fix is to preserve the quotes around a local-part
name in an address.

Test:

	import rfc822
	a = rfc822.AddrlistClass('(Comment stuff) "Quoted
name"@somewhere.com')
	a.getaddrlist()

The correct result is:

	[('Comment stuff', '"Quoted name"@somewhere.com')]
