Yes.

I am not sure,

 * jed is still a bit smaller than xjed (although the difference of
   226264 - 187704 bytes might be negligible), but

 * installing less packages is nice. 
 
so we could possibly give the users/administrators a choice.

(We could even consider abadoning the jed/xjed separation and provide
just one "jed" package with xjed and the wrapper script.)

We should definitely add a comment and we should IMHO also provide the
abovementioned shell script with the "xjed" package. 

I am not sure about a nice mechanism to install the script automatically
in the PATH but let the "jed" package replace it with the jed binary.

 * install the jed shell script in /usr/bin/X11 (so the /usr/bin/jed
   binary takes precedence)

or 

 * let xjed and jed conflict and let xjed provide the shell script as
   /usr/bin/jed

For a test, I saved this as /usr/local/bin/jed and now jed on an xterm
will call xjed (as checked by ps) but behave as Jed:

   message("You run "+
   #ifdef XWINDOWS
           "XJed"
   #else
           "Jed"
   #endif
           );
   
says "You run Jed" and
   
   if (is_defined("x_insert_selection"))
     message("x_insert_selection is defined");
   else
     message("x_insert_selection is not defined");

says "x_insert_selection is not defined".
