+  o Minor bugfixes (practracker):
+    - When running check-best-practices, only consider files in the
+      src subdirectory.  Previously we had recursively considered
+      all subdirectories, which made us get confused by the
+      temporary directories made by "make distcheck".  Fixes bug
+      31578; bugfix on 0.4.1.1-alpha.
