It is problematic when you try to apply a hunk via C-c C-a because any
empty line following your hunk (e.g. the last hunk in a C-x v =) will be
taken as being part of the hunk and C-c C-a will think that the original
text was just missing a newline and will add it (as a result of its
fuzzy matching feature).
