I don't mean to do that in general, but to add such a
suppressing code somewhere in this calling sequence:

For instance, introducing a global variable
`inhibit_loading_message', toggle it on and off around the
code of evaluating a form in display_mode_element, and
modify Fload to pay attention to it.

This is just a quick thought.  For the correct fix, we have
to study the code more.   For instance, I don't know why
echo_area_display must lead to redisplay_mode_lines.

But, for the moment, I don't have a time to study this issue
in detail and write an actual code.
