Ok, I thought that "C-s", when invoked from the minibuffer, was
intended to search _only_ through the minibuffer history (like
"M-s"/"M-r" do), not also in the current minibuffer text.  I should
have read info node "(emacs)Isearch Minibuffer" before submitting this
bug report, sorry.

Now that I understand it, I'd like this bug report to become a feature request:

IMO, It isn't worth making C-s (and C-r, C-M-s, C-M-r) look up also in
the current minibuffer text, because it is usually small enough not to
need that (how often do you use that feature?).

I'd like these commands (C-s, C-r, C-M-s, C-M-r) to be similar to M-s and M-r:
* Focus exclusively in the minibuffer history.
* Have a minibuffer-specific prompt ("Next/Previous element matching
[regexp]: ") so that it is clear what's going on.
* Obviously, clear the minibuffer's previous input.
