Prepend the above command with something like 'COLUMNS=200 ' to see full package
names.

For me, this p_list now includes packages that I have deinstalled, and
dpkg --get-selections shows them as deinstalled. I believe if you use
this p_list you may try to install *all* available packages found in
your sources.list rather than just the packages you have installed
currently.
