  Emacs/W3 already deals with all the parsing and crap for mailcap and
mimetypes files, and allows you to specify lisp-viewers from within a
mailcap file.  Right now it uses 'is the first character of the viewer a
quote' to determine if it should be treated as an internal function.

  I could change this to x-emacs-viewer or something like that pretty
easily.  The appropriate file in Emacs/W3 is mm.el - it can be drastically
improved pretty easily, and it is already signed over to the FSF since
1996. :)
