bug#14188: 24.3.50; ODF files and auto-mode-alist

[Stephen Berman <stephen.berman@gmx.net>]

The extension .od[fgpst] for ODF files occurs twice as part of a key in
the default value of auto-mode-alist, paired first with archive-mode and
later with doc-view-mode-maybe.  As a result, visiting such a file shows
the directory-style listing of the archive instead of the files content.
To see the latter, you have to explicitly invoke doc-view-mode.  But if
.od[fgpst] is removed from the key paired with archive-mode, then
visiting such a file shows the content after conversion, and when you
type C-c C-c, it switches to the archive listing, due to
magic-fallback-mode-alist.[1]  I think this is better behavior.  I can't
test files with the other extensions in the problematic entry
("\\.\\(sx[dmicw]\\|od[fgpst]\\|oxt\\)\\'" . archive-mode), so I don't
know if the whole entry should be deleted or only "od[fgpst]\\|".

Footnotes: 
[1]  Actually, it only switches to the archive listing if the global
value of major-mode is fundamental-mode.  I don't know if this is a bug,
so I'll ask about it on emacs-devel.
