@Josy: Alas, the output from dpkg -l is truncated to make room for the version number and short description. In the general case, you can use something like COLUMNS=200 dpkg -l whatever; but in this particular case, the packages you want to remove are the ones you have installed in /var/lib/dpkb/info i.e. xemacs21-mule and xemac21-support. (The "un" in the first column of dpkg output means not installed.)
