* plugin-runner.c (main): Bug fix; do not accept a "d" character after

                          "%u" when printing PID of coredumped plugin,
                          not "%d".
* plugins.d/password-prompt.c (main): Remove comment which was copied
                                      from another program by mistake.
* plugins.d/splashy.c: Only comment changes.
