This is not related to screen - it is a feature of ksh, as Dieter wrote.
You just have to start PS1 with ^A^M. So, my fragment of shrc to set
prompt now looks like:

                ptput()
                {       echo -n "\001"
                        tput "$@"
                        echo -n "\001"
                }
                nastavprompt()
                {
                        typeset STR;
                        if [ $(id -u) = 0 ];
                                then STR='#';
                                else STR='$';
                        fi;
                        promptpath ()
                        {
                                if [ "${PWD##${HOME}}" = "${PWD}" ];
                                        then echo "${PWD}" ;
                                        else echo "~${PWD##${HOME}}" ;
                                fi;
                        };

                        PS1="^A^M$(ptput AF 2)${LOGNAME}@$(/bin/hostname -s):\$(
promptpath)${STR}$(ptput AF 7) ";
		}
