+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.
