Do you have the original email message some place?

There is an odd case where if someone put the From: header
in the middle of the text that we now notice and process and I
didn't feel right about removing a line from the middle of the
text.

I was fixing a nasty corner case that happens if there aren't any
mail headers at all passed to git-mailinfo.  Where we could drop
lines without processing them at all.

This doesn't look like the From: header was in the middle of the
message until it was imported into git so it is probably a small
logic error that is easily corrected.  But I need to see what
we are parsing so I can understand what is happening.

where that "From:" in the body is totally wrong. I just didn't notice, 
until now. Arrr!

I _suspect_ that this is the work by Eric Biederman, ie part of the 
patches that do "Allow in body headers beyond the in body header 
prefix." and "Refactor commit messge handling."

Eric? Can you please fix this up? Lines from the body of the email that 
have been used to set authorship should _not_ also show up in the commit 
message.
Even if the header lines are in the middle of the body?

No, it's at the top of the body, although there might have been an empty 
line or two (ie whitespace only) before it.
Even if the header lines are in the middle of the body?
What do you mean by "middle"?

No, it should only look at From: and Subject: lines if they are at the 
very top, with no other non-whitespace lines above them. But when it looks 
at them and uses the data from them, it should then remove them from the 
body - they are "conceptually" just extended header lines that just 
happened to technically (from an rfc822 standpoint) be in the body of the 
email.

I hate to say this, because I'm bad about it, too, but we should
probably have a few tests for applymbox, to cover the various scenarios
discussed in this thread.
