-Subject: [PATCH] tests: Fix a test failure in test-transaction.scm.
-
-With the New Year upon us, a test which was hard-coded to use 2018 now
-failed.
-
-Fixes issue #797008 (see:
-https://bugs.gnucash.org/show_bug.cgi?id=797008).
-
-* gnucash/report/standard-reports/test/test-transaction.scm:
-(trep-tests): Use the current year in the test string instead of a
-static one.

+Subject: [PATCH] Add installation directory as a default directory.
+
+In Guix, this library is installed in a separate directory in the store,
+and it's typically not installed system-wide in a fixed directory. Add
+the store path to the set of default directories so dependents can find
+default langs and source highlighting scheme.
