+       Let the initial-action act on the look-ahead, and use it for the
+       "initial push" (corresponding to an hypothetical beginning-of-file).
+       And let lalr1.cc honor %initial-action.
+
+       * doc/bison.texinfo (Initial Action Decl): Clarify, and add an
+       example.
+       * data/lalr1.cc (Parser::initlocation_): Remove, bad experiment.
+       (Parser::Parser): Remove the ctor that used to initialize it.
+       (Parser::parse): Like in the other skeletons, issue the "starting
+       parse" message before any action.
+       Honor %initial-action.
+       Initialize the stacks with the lookahead.
+       * data/yacc.c: Let $$ and @$ in %initial-action designate the
+       look-ahead.
+       Push them in the stacks.
+       * tests/actions.at, tests/calc.at: Adjust the C++ ctor invocations.
