Good.  But I don't see where you documented parameter BEGINNING.

Dunno what that means.  Motion keys will yank or delete?
Doesn't sound too good, a priori.
Guess I missed the functional spec for that. ;-)

Why not just reuse the keys we already use to yank, but have them yank
at the beginning when you search in reverse?  E.g.:

C-w     - `isearch-yank-word-or-char', but at the beginning.
C-y     - `isearch-yank-kill', but at the beginning.
C-M-y   - `isearch-yank-char', but at the beginning.
M-y     - `isearch-yank-pop', but at the beginning.
M-x C-e - `isearch-yank-line', but at the beginning.

Doesn't that seem natural?

In Isearch+ I have even more than that for yanking.  I would much
rather have a user be able to reuse the same keys in the opposite
direction.
