-Subject: [PATCH] Mark more tests that require the network
-
-I believe all these tests require the network, at least they seem to
-fail if it's I run them without connecting my computer to the web.
-
-I'm looking at this as part of packaging linkchecker for GNU Guix,
-where the package is build and the tests are run in a isolated
-environment, intentionally without network access, to avoid issues
-with non-reproducible package builds.

+
+This patch was prepared for Guix by Jack Hill <jackhill@jackhill.us> by
+squashing together the changes from upstream #268
+<https://github.com/Tlf/tlf/pull/268>.
+
+It allows the released version of Tlf to build against the version 4.2 of
+hamlib in Guix.
