    Correctly honour theme foreground colour
    
    Rather than try to explicitly look up the colour, don't specify a colour
    at all. Argument names are never nested within a <span> applying a
    different foreground colour.
    
    This does have one visible effect: with Adwaita (light), selecting the
    treeview row causes method argument names to switch from black to white,
    just like the method name. I think this is actually more readable (and
    the green used for the signature is illegible against the blue
    selected-row highlight.)
    
    As discussed in https://gitlab.gnome.org/GNOME/d-feet/merge_requests/4#note_319094 and !8.
