Fix the mutt query "single line message" string for h2s/ppl#20
Strip out  characters from all output to fix part of h2s/ppl#27

Part of me is a little concerned about doing this as I'm imposing quite an
arbitrary limitation on what is and isn't acceptable vCard content by doing it.
Hopefully this won't screw any Windows users.
