Make Debian-specific tweaks to xterm:
* Set the default VT widget foreground and background colors to gray90 on
  black, which approximates the color scheme of the Linux virtual console
  (and approximates actual DEC VT terminals far more closely than
  black text on a white background in any case).
* Stop using an Xaw7 gradient for the backgrounds of the xterm menus; it
  produces an unappealing effect if the menus are configured to use a
  larger font than the stock configuration (also, xterm has added items to
  some menus since I last calculated the gradient size and I can't be
  bothered to do it again).
* If the X server is capable of color and has more than 8 planes of color
  depth available, set the menu colors to gray15 on antique white, and
  customize the appearance VT widget's scrollbar.  Otherwise, do not eat up
  precious entries in the color palette.
* Set the "backarrowKeyIsErase" and "ptyInitialErase" parameters to true by
  default.
* Define the "xterm-debian" terminal type in the termcap and terminfo
  files; it is based on "xterm-new" with the exception that the backspace
  is VT220-conformant, as directed by section 9.8 of the Debian Policy
  Manual.
