It should at least warn when --in-reply-to=<email_file> is not given
(either no --in-reply-to or --in-reply-to=<id>). I don't see any
use-case where a user would want --cite on the command-line and not want
--in-reply-to=<email_file>. OTOH, it seems a plausible user-error, and
the user would appreciate a message saying what's going on.

Just wondering: would it make sense to activate --cite by default when
--in-reply-to=file is used, and to allow --no-cite to disable this?

This is something we can easily do now without breaking backward
compatibility (--in-reply-to=file doesn't exist yet), but would be more
painful to do later.

Nit: I read "$message_cited" as "Boolean saying whether the message was
cited". $cited_message would be clearer to me (but this is to be taken
with a grain of salt as I'm not a native speaker), since the variable
holds the content of the cited message.

I would add a newline here to get a blank line between the message cited
and the diffstat.

I think non-ascii characters would deserve particular attention here
too. For example, if the patch contain only ascii and the cited part
contains UTF-8, does the generated patch have a proper Content-type:
header?

I can imagine worse, like a patch containing latin1 character and a
cited message with another 8-bit encoding.

I would prefer to have the full address including the real name here (A
<aut...@example.com>) in this example. Actually, after a quick look at
the code, I don't understand where the name has gone (what's shown here
is extracted from the From: header).
