    This would be actually great, it would match the behavior of standalone
    info (which, IMO, is much better).

    Is there any reason not to check this code in?

I like being able to confine an isearch to the current node. Currently, I
can use `s' for global search and `C-s' (or `C-M-s') for local (node)
search.

So, to me, it would be desirable to have some indication that the end of the
current node was reached without finding another occurrence of the string -
e.g. "Failing isearch in node Foo: bar". Except for being able to overwrap
isearch in the node (no great loss), this would give the advantages of both
approaches (local and global search). Without such a local-failure
indication, you would have to (perhaps unwittingly) continue the search to
another node, and then use `l' to get back where you were.

IOW, why not have two levels of isearch "failure": 1) no more in the current
node, 2) no more in the current Info "manual"?
