The piping to sort relies on inserting a space. Without the space,
you'd be sorting on package version numbers, doh!, but yes, trying to
get this included upstream might be a good idea.
# `dpkg-query -W` already sorts on package name. It's just that diff
# only looks at what it gets. The `sort` I added is after the egrep.
Hope this helps,
