Hmm, but that is different, isn't it?

AFAIK people use this format:

---
$headers

Message

Patch (format-patch output: headers, commit message, diff)
---

In this case 'git am' would ignore the patch headers. The only way
'git am' would override $headers, is if the first part of the body has
new headers:

---
$headers

$patch_headers

$patch_commit_message

$patch_diff
---

IOW; if there's no message at the beginning of the body.

I can't foresee that, but I guess we can do it anyway. So which would
be the fields to repeat? From, Date, and Subject?

I meant I wanted to know which fields would be useful to put in the body.

Cheers.
