    quickreference: fix quickreference generation.
    
    On my machine, I get an "Unknown output format". I'm going to assume it
    works on some other cases which are not case-aware, but that the
    lowercase version would work everywhere (hopefully not breaking it for
    someone else).
    
    (cherry picked from commit 15551c347a0b881910a977c86c543e355360a1e1)
