It moves in the right direction, but it isn't enough. I don't recall the
specifics, but I think it has conditional placeholders for things like
"if this is non-empty print it". But there are still some problems:

  - the ref-filter formatting isn't unified with the commit
    pretty-printer formatting. So this wouldn't help for a traversal,
    anyway.

  - the decoration thing needs a new placeholder. "%d" means "always
    show the decoration", but the OP really wants "show the decoration
    if the user asked for decorations, and empty otherwise".
