I think the first two shouldn't even be in isearch.el. There's a ton of
stuff in isearch.el that's just generally useful in searches (nothing
specific to incremental search), and should be moved to some search.el
file.

I don't see what these have to do with the readability of isearch el, but
by all means, feel free to do these. 👍
