Most of the latin-N input methods made a lot of sense in Emacs-22 where
the chars were not unified.  Now that they're unified, the distinction
is not nearly as important, so I'm in favor of merging/removing most of
those methods, keeping just some generic "latin" input method maybe,
plus the language-specific ones of course.

The impact it may have on the encoding used when saving the file is best
tackled elsewhere.  E.g. if the user's preferred coding systems
indicate that latin-1 is preferred over latin-9, then saving a file as
latin-9 in the absence of any coding cookie should prompt the user,
explaining that Emacs will mis-detect it as latin-1 next time around.
