I agree that this solution is much better than the initial one "discarding
by space".
I would start to implement this one.

I think all this could be done by a combination between toggling the status
of
the `history-add-new-input' variable and a mode-line indicator (or a
different
face or background for the strings written in the minibuffer).

To switch the history variable while you are typing at the minibuffer seems
more
complex and confusing, because this could have conflicts with the variable
from
which you can currently recall previous commands or text.


By the way, several years ago I wrote `minued', a minibuffer history editor
for JED
http://jedmodes.sourceforge.net/mode/minued/
Is there something similar for Emacs?
Do you think it would be worth having it for Emacs?
