The copyright dates in the manpages haven't been updated in awhile.

Also, when pod2man converts a pod file into a manpage, it will only
remove the extension from the filename if it is ".pod". Some of the
libvirt pod files are named *.pod.in, and that filename is placed
unchanged into the manpage. This patch uses pod2man's --name option to
fix that.

Believe it or not, there's even a BZ for this:
