Re: Avoiding moving point into minibuffer prompt area

    I would just like... point to stop where it is then.

Normally, delete-backward-char at the beginning of the buffer
gives an error, "Beginning of buffer".  It would seem strange
if, when just after the prompt, it did nothing at all.

    In the minibuffer there is by default (emacs -Q) no color that tells 
    where the prompt ends.

The prompt uses the face `minibuffer-prompt'.  Are you saying this
does not work for you?  It works for me.

It is hard for me to understand the rest of your message.  It seems
to cover many topics and I do not see the relationship between them.
