Reading this, I was at first concerned that you were using "bold" and
not DIFF_METAINFO. But:

This is correctly passing the DIFF_METAINFO color, which is in the "set"
variable. Good. I looked at the output on a sample repository, and it is
much easier to read (though I use magenta for my metainfo).
"set" is a terrible name for that variable (not your fault, of course).
When you re-roll (and I think you need to because of the diff_ui thing
in patch 2), would you mind throwing this cleanup in the middle?

Subject: builtin_diff: rename "set" variable
Once upon a time the builtin_diff function used one color, and the color
variables were called "set" and "reset". Nowadays it is a much longer
function and we use several colors (e.g., "add", "del"). Rename "set" to
"meta" to show that it is the color for showing diff meta-info (it still
does not indicate that it is a "color", but at least it matches the
scheme of the other color variables).
