It wouldn't be very hard to ask format-patch to just handle this
unconditionally. Something like:
diff --git a/pretty.c b/pretty.c
index e4ed14effe..9cf79d7874 100644
--- a/pretty.c
+++ b/pretty.c
@@ -451,7 +451,8 @@ void pp_user_info(struct pretty_print_context *pp,
map_user(pp->mailmap, &mailbuf, &maillen, &namebuf, &namelen);
if (cmit_fmt_is_mail(pp->fmt)) {
- if (pp->from_ident && ident_cmp(pp->from_ident, &ident)) {
+ if (pp->always_use_in_body_from ||
+ (pp->from_ident && ident_cmp(pp->from_ident, &ident))) {
struct strbuf buf = STRBUF_INIT;
strbuf_addstr(&buf, "From: ");
but most of the work would be ferrying that option from the command line
down to the pretty-print code.
That would work in conjunction with "--from" to avoid a duplicate. It
might require send-email learning about the option to avoid doing its
own in-body-from management. If you only care about send-email, it might
be easier to just add the option there.
