Ok. As far as I understand, a search will use `search-spaces-regex' in
place of an explicit space entered by the user at prompt.

So I could use this to match separators (and newline) when a space is
entered but it won't automatically «jump» soft newlines as I wanted.

Example with this longlines-mode content:
--8<---------------cut here---------------start------------->8---
Element1|Element2|
Element3|
--8<---------------cut here---------------end--------------->8---

Searching for "|Element3|" won't match but I could use
`search-spaces-regex' to make searching for " Element3 " match. What do
you think?
