1) `-x foo` currently dumps one `foo`. This change makes it dump all `foo`. 2) `-x foo -x foo` currently dumps `foo` twice. This change makes it dump `foo` once. In addition, if foo has section index 9, `-x foo -x 9` dumps `foo` once. 3) Give a warning instead of an error if `foo` does not exist. The new behaviors match GNU readelf. Also, print a new line as a separator between two section dumps. GNU readelf uses two lines, but one seems good enough.
