Sorry for this late reply. I've been quite busy lately..

I think I just happened to reuse the style of the old
format_decoration(). Will reuse the name "decoration" instead.

legacy from pretty.c:format_decoration(). Will move it to the caller
format_commit_one.

Yes, your eyeballs have really good quality ;)

I think it's a sane convention, unless we want a some background color
going through show_decorations.

No problem.

All in one, apparently. Will rename.
