I guess that patch would work, but somehow ielm's calling comint's
output filter on read-only text seems vaguely dodgy to me.

Perhaps it would be better to make comint itself support read-only
prompts, controlled with a variable; then ielm could just set that
variable to t.  That would be a useful feature that people could turn
on for other comint modes as well if they want.

[An alternative might be to have comint support having only the
_current_ prompt be read-only, since it's usually only that one which is
in danger of being inadvertently modified.]

Come now, if we were really planning to harm you, would we be waiting here, 
 beside the path, in the very darkest part of the forest?
