In our codebase, please make asterisks stick to the variable not the
type, i.e.
const char *prefix,
const char *separator,
const char *suffix)
Was there a reason why "sep" alone needed to be abbreviated?

Have SP between the control statement (i.e. not a function name) and
its opening parenthesis, i.e.
if (decoration->next)

Hmph. I was kind of found of the nice trick to use a punctuation,
which first points at the prefix " (" and then later points at the
separator ", ", to allow the code that prefixes the punctuation
before showing a new item. It is now lost.

Linewrapped by your MUA, perhaps?
Again, please check where your asterisks are.

My eyes hurt staring at this line and the same one in the other
file, trying to see which comma is which.
I wonder if doing something like this once at a single place:
#define format_decorations_std(strbuf, commit, color) \
format_decorations((strbuf), (commit), (color), " (", ", ", ")")
and using
format_decorations_std(sb, commit, opt->diffopt.use_color);
format_decorations_std(sb, commit, c->auto_color);
or even better, name the one that takes three extra parameters as
format_decorations_extended(), and keep the behaviour of the
original one the same, i.e.
#define format_decorations(strbuf, commit, color) \
format_decorations_extended((strbuf), (commit), (color), " (",
", ", ")")
That way you do not have to touch the original callers, nor you
would have to worry about breaking any topic that somebody else may
be preparing that adds new calls to format_decorations().
