My background is LightYellow (and there are some more light schemes
around, so I suppose I am not alone). This is why I suggest "borrowing"
colours from the ones defined in the standard colour schemes. 

This will

 * work out of the box for both, light and dark background,
 * use colours that fit in the overall scheme,
 * enable user customisation without interference on the "standard"
   colours using something like
     define_color("diff_block", "black", "yellow");
   in the jed.rc file.  
   

My suggestion for the mapping of "standard" to "diffmode" colours is:

  % Default colour scheme
  
  custom_color("diff_cmd",     get_color("operator"));    % diff
  custom_color("diff_oldfile", get_color("bold"));        % ---
  custom_color("diff_newfile", get_color("number"));      % +++
  custom_color("diff_block",   get_color("preprocess"));  % @@
  custom_color("diff_deleted", get_color("error"));       % - or <
  custom_color("diff_added",   get_color("keyword"));     % + or >
  custom_color("diff_junk",    get_color("comment"));     % Only / Binary
  

Could we agree on such a colour setup?

Could you try whether this works out to your convenience with a dark
colour scheme and maybe mail suggestions for change?
