If you unpack the package somewhere, either using ar etc or,
more easily, by selecting it in mc and copying CONTENTS into,
$ for j in $(dpkg -L packagename) ; do [ -f $j ] && diff -u $j /tmp/CONTENTS/$j ; done
will list any changes. For example:
$ for j in $(dpkg -L initramfs-tools) ; do [ -f $j ] && diff -u $j /tmp/CONTENTS/$j ; done

Add quotes "" to taste. And you may need to chmod u+w /tmp/CONTENTS
to clear it out when finished.
