I mean "forgotten" variables and functions that were never intended to 
be exported. I know that in Elisp all identifiers with file scope are 
exported, but it would be nice to at least have a list of all 
declared-but-never-used-in-the-same-file identifiers. That would give 
you an hint of what can safely be removed.
