PATCH: update mutt and irssi completions

[Oliver Kiddle <okiddle@xxxxxxxxxxx>]

The additional mutt options are perhaps for the development branch but
that seems to be what every Linux distribution is including. For irssi,
there was only one extra option and not a very exciting one at that but
it is good to have it up-to-date.
