Keeping it in small does give less strain to the eye ;)

Initially I was using strbuf but then I switched to const char *
according to Junio's suggestion. It seems that in this version I have

I agree that it is confusing. I couldn't find a better way to describe
it and since this would be gone after the whole conversion, I didn't
bother putting more efforts there.
