it took me a while to realize the change, but it's really cool, thanks!

continuing the search from the current "cursor" position is intuitive
and also what most (all?) users expect, so fwiw i'm ok with the diff.

one minor nitpick below

please, wrap nested ifs like these in braces.

		if (view->searching == TOG_SEARCH_FORWARD) {
			if (...)
				...
			else
				...
		} else {
			...
		}

while you're code is correct and even without indentation there aren't
other ways to interpret it, the "dangling else" can be confusing :)
