commit 521398d3903cc0478087d0183157e9f70f533381
Author: Fabian Keil <fk at fabiankeil.de>
AuthorDate: Fri Jun 20 13:40:47 2025 +0200

    Rename connection_header_contains_keep_alive_keyword()
    
    ... to keep_alive_keyword_detected() as the function may
    return FALSE if there are "too many" keywords.
    
    Document this behaviour explicitly.
