示例1: log_line
/** \brief Parse one line of log.
*
* This function reads one line of log. Note that one line of log may appear
* on multiple lines in the changelog file. One line ends when there is an
* empty line, a line that does not start with at least 2 spaces, a line
* that starts with an asterisk after the 2 spaces.
*
* \param[in] s The state describing the input parameters.
* \param[in] group Whether this log is a group entry.
*
* \return true if the end of the file was not yet reached.
