+Subject: [PATCH] debian/copyright: drop obsolete FSF street address
+
+The 'You should have received a copy ... write to the Free
+Software Foundation, Inc., 51 Franklin Street, Fifth Floor,
+Boston, MA 02110-1301 USA' paragraph flags the lintian tag
+'old-fsf-address-in-copyright-file'. Debian prefers either no
+address at all or an https://www.gnu.org/licenses/ reference;
+in this file /usr/share/common-licenses/LGPL-2.1 is already
+cited a few lines below, so the address is redundant. Replace
+with the gnu.org URL per current FSF boilerplate.
+
+Pre-existing text, no change to the licence terms.
