+ Update some comments to make sense for -D.
+ * data/bison.m4 (b4_check_user_names): In header comments, say
+ "user occurrence" instead of "grammar occurrence".

+
+ Handle a trailing `:' in a user-supplied C++ namespace better.
+ * data/c++.m4 (b4_namespace_close): Don't let it be printed
+ among the closing braces here. This fix might make the
+ generated code easier to debug, but otherwise it should be
+ insignificant because a trailing `:' is a C++ error already.
