Very nice introductory patch.

In Git's source code, we skip the curly braces for one-liners.

This could be folded into the previous conditional:
}
else {
int n = arg ? strtol(arg, NULL, 10) : 1;
...
Having said this, ...

How about using a COUNTUP here instead? We could then set the status
format afterwards, like this:
if (porcelain == 0)
status_format = STATUS_FORMAT_UNSPECIFIED;
else {
status_format = STATUS_FORMAT_PORCELAIN;
if (porcelain > 1)
warning("No porcelain v%d; falling back to v1",
porcelain);
}
The rest of the patch looks good to me!
Ciao,
Johannes
