* the sed that works has a backslash before the '+'; the sed that doesn't
lacks this backslash.

* consider using sed -r and extended regular expressions; this will remove
the need for these backslashes.  I think this would work:

dpkg-parsechangelog | sed -r -n -e "s/^Version:
[0123456789.]+-([0123456789]+)$$/\1/p"

PS. Thanks for updating aunit.
