The culprit seems to be this change:

  2011-02-12  Eli Zaretskii  <eliz@gnu.org>

          * terminal.c (create_terminal): Use default-keyboard-coding-system
          and default-terminal-coding-system to initialize coding systems of
          the new terminal.  (Bug#7840)

produced by the RET key.  Hmm...
