Re: ielm working buffer on the modeline

[Richard Stallman]

    What about changing the buffer name rather than the mode-line-process, ie.

            *IELM on test.el*

    or

            *IELM on *wide reply to Juanma Barranquero**

In case there is more than one IELM buffer pointing at the same
long-named buffer, it would be important to uniquify the names in
a somewhat special way.  The difference between
*IELM on *wide reply to Juanma Barranquero**  and
*IELM on *wide reply to Juanma Barranquero**<2>
would not be visible in the mode line.
