[Tagging] Automatic edit: access=visitors --> access=customers

[Sören alias Valor Naram]

Hi,

I
cumberstoned over `access=visitors` which is not documented and which I
and also others believe should be `access=customers`. This would be a
less problematic automatic edit you will definitely like and which can
show how important and sometimes unproblematic they are.

Before writing
a proposal for it I'm willing to hear your thoughts on this. I also
believe that automatic edits help to correct tagging mistakes when done
properly and following UNIX philosophy.

Cheers
