    Accept -? for glib-mkenums.
    
    Commit 789e260638d tried to add support for -?, but there is a typo
    and instead -h was added when already present instead of -? for one
    of the cases.
    It works without this corrections, because all unrecognized options
    trigger usage showing as well, but this is more correct.
    
    This was bug 556706 originally.
