Will do s/breakes/breaks/ while applying.

It makes me wonder, however, why it is a good idea to have the I-R-T
in the format patch output in the first place.

I can see how this would work the way it should for the first
message we send out, so it would work well for a single patch.

But what does this change do to the chaining (either making [PATCH
1/N] thru [PATCH N/N] as responses to the cover letter [PATCH 0/N],
or making [PATCH n+1/N] as response to [PATCH n/N] for 1 <= n < N)
of multiple messages?

When you prepare a series whose 1..N/N are all pointing at 0/N with
the already prepared In-Reply-To (so you have N+1 files to send
out), wouldn't you want to make 0/N a reply to a particular message
you specify on the command line, while keeping the relationship
among your messages intact?  Doesn't having $initial_in_reply_to
(i.e. command line override) help above code break the chaning?
