Ok, this patch fixes this issue plus the "open dvi/pdf files with
doc-view and ps-files with ps-mode by default" issue.  (See message
<877ilj45zn.fsf@baldur.tsdh.de> and its follow-ups.)

The only thing that remains is to find another keybinding for toggling
between editing and viewing with doc-view, because ps-mode already uses
`C-c C-c'.  Suggestions?

The patch is also at http://www.tsdh.de/stuff/doc-view.patch

Bye,
