+       maint: clean up update-b4-copyright code
+       * build-aux/update-b4-copyright: Do not accept 2-digit
+       UPDATE_COPYRIGHT_YEAR, which was not handled correctly.
+       Don't accept a `[' in a b4_copyright argument.
+       Format code more consistently.
+       Don't assume b4*copyright never occurs.
