OK.

(But I can guess the outcome.  It's OK; I can always
just add the enhancement to isearch+.el.  It won't be
the first time.)

FYI, it doesn't do that in the parts that are doc.
Those patch parts still speak of `C-M-c'.

FWIW, I don't think that's really TRT.

Personally, I have `case-fold-search' set to nil by
default, so that behavior isn't a problem for me.
But I don't think it should be part of this command.

Users can toggle case-folding in Isearch easily.

There's no reason to have this command make an
assumption about whether its char-search should be
case-sensitive.  I don't think the either...or
assumption you made above is good for the command
to make.  Better to let users control whether to
search for the char case-sensitively.
