pkg_rmleaves regresssion

Hello.

I'm a long time user of pkg_rmleaves, but, after the last update, I'm 
experiencing a problem.
The first run works fine, but, after that, the same packages appear 
again and again, with the new leafs at the end of the list.

I think the problem lies at the beginning of the showList() function, where
>         cat "$TMPFILE" >> "$DLGFILE"
should be
 >         cat "$TMPFILE" > "$DLGFILE"

Thanks for providing this port.

  bye
