I think the variables I listed are safe to delete.  But in general I
don't think there's any way to determine it automatically.

For example the function `mm-file-name-collapse-whitespace' isn't used
anywhere -- but its purpose is that you can add it to the hook
`mm-file-name-rewrite-functions', so it clearly shouldn't be removed.
