Ok, that makes sense.

Hm, I see the message with M-x when I open some file for the first time.
Thereafter, it shows the key binding instead...

I've now committed the change you suggested initially, that is, I've
removed the OpenDocument and StarOffice file extensions from the
archive-mode entry.  One exception is *.OXT which is an OpenOffice
extension pack that has no visual representation.

So now doc-view-mode-maybe is the default for StarOffice/MSOffice/
OpenDocument files instead of archive-mode with the possibility of
falling back to that with a simple C-c C-c.

I'm closing this bug now.

Thanks,
