Bug#164021: xterm: Removing manually selected alternative

[Richard A Nelson <cowboy@vnet.ibm.com>]

Package: xterm
Version: 4.2.1-2
Severity: normal

Everytime X is upgraded, I have to go through the following...
isn't there some way to only remove the alternative if it would
no longer work ?

...
Setting up xterm (4.2.1-2) ...
Removing manually selected alternative - switching to auto mode
...
# update-alternatives --config x-terminal-emulator

There are 8 alternatives which provide `x-terminal-emulator'.

  Selection    Alternative
-----------------------------------------------
      1        /usr/bin/xvt
*+    2        /usr/X11R6/bin/uxterm
      3        /usr/bin/Eterm
      4        /usr/bin/aterm-xterm
      5        /usr/X11R6/bin/xterm
      6        /usr/bin/wterm
      7        /usr/bin/rxvt-xterm
      8        /usr/bin/rxvt-xpm

Enter to keep the default[*], or type selection number: 8
Using `/usr/bin/rxvt-xpm' to provide `x-terminal-emulator'.
