    fuzzy: keey the case-sensitive sort branch out of the hot path
    
    If we are not in bulk insert, then the extra walk of the string is not
    nearly as expensive as the common case of bulk insert.
    
    This saved about .2 seconds (from 1.2 to 1.0) on a test case of 150k
    files (using gecko-dev).
