There is sort-dctrl which would not fail in that case. It seems most
(all?) tools are producing Packages files with two trailing newlines
anyway.
Sort-dctrl is also much faster than apt-cache show for this, and will
not miss anything arch-wise (assuming Dir::State::Lists is at it's
default value).

No need to concatenate files for that. ?
