os: search in temporary buffer instead of string 

Instead of filtering all lines for `PRETTY_LINE` and then replace the
line with only the quoted contents, `re-serach-forward` (or -backward)
provide a `match-*` interface. That way we can work solely inside the
buffer and return only the matching string part.
