Subject: [PATCH] Fix paste error in the new pq_concatenate.

Commit 6a5d4d083 introduced a foolish list-handling bug: concatenating
a non-empty queue to an empty queue would set the tail of the output
list to the _head_ of the non-empty one, instead of to its tail. Of
course, you don't notice this until you have more than one packet in
the queue in question!
