- it's where the recursive search is implemented.

As you'll see it's using the \Q...\E delimiters in the search expression 
to explicitly disable use of user provided regexes. The problem is that 
not doing so might accidentally break the search if somebody 
accidentally used a character which might be interpreted as a regex.
