R*search and R*SEARCH are just meant to indicate a
regexp pattern (the former indicating case-sensitive).

The Isearch+ doc says what it means.  But I don't say
you need to follow what I did exactly.

The point was just to say that with very little screen
real estate (a mode-line lighter) we can show, and
dynamically update, a fair amount of info about the
current Isearch state: whether case-insensitive, and
whether regexp searching.

I intend it only as food for thought.
