I did a bit of testing of the vacation program (my Debian edition), and I
checked the source code, and it appears there isn't the option of separating
multiple aliases with commas.

So now I can't think of any situations where rfc822_explode will have an
advantage over regular explode (well... only some very peculiar ones).
Perhaps I missed something, but otherwise you could consider saving those
extra lines of code.
