It should probably get the same treatment, though I think the module boundaries make it a little more awkward. We look at it in diff_flush(), which otherwise doesn't need to know much about the pretty-printing. Perhaps stat_sep should be a callback? > diff --git a/pretty.c b/pretty.c > index d0f86f5d85..56e668781a 100644 > --- a/pretty.c > +++ b/pretty.c > @@ -1641,6 +1641,21 @@ void pp_title_line(struct pretty_print_context *pp, > if (pp->after_subject) { > strbuf_addstr(sb, pp->after_subject); > } > + if (pp->print_email_subject && pp->rev && pp->rev->mime_boundary) { > + strbuf_addf(sb, > + "MIME-Version: 1.0\n" In the original, this would have been in "after_subject". Which means we would print it even if print_email_subject is not true. Why do we need to check it in the new conditional? Not that I expect the behavior to be wrong either way; why would we have a mime boundary without setting print_email_subject? But I would think that "do we have a mime boundary" would be the right conditional to trigger printing it. -Peff
