Just a note to other reviewers: I found it odd to call a function with
one argument and then enforce list context, but I see expand_aliases()
expects to be called that way, and this is copied from a previous
pattern earlier in the file.

(As an aside, that code looks a bit odd, but then I see 302e04ea4d
("send-email: detect cycles in alias expansion", 2009-07-23) )

Looks good to me.
