Since this can of worms has been opened and stirred...

FWIW, I disagree with the approach being considered (Juri's suggestion etc.). It
is complicated for nothing. The simplest approach is the best: C-h during
isearch should give the isearch bindings - bind C-h to `isearch-mode-help'.

That is the convention, and it is a good one. This is like C-h following any
other prefix key. Richard is just wrong about this. Why jump through hoops?

If you are isearching and you want the global help, then (guess what?) you
simply exit isearch: RET or whatever. Nothing hard about that.

Nothing new here. No need for fancy, inconsistent stuff. No need to complicate
the UI. Just C-s...C-h to see the isearch bindings and C-s...RET C-h to see the
global help.
