bug#19726: 24.4; When sending email, all lines starting with `from' get capitalized

[Marek Rudnicki]

Hi,

I'm using GNU Emacs 24.4.1 on FreeBSD and GNU/Linux.

I noticed a strange behavior, that whenever I send a GPG signed email
from Emacs, all lines in the body (and inline attachements) starting
with `from' followed by some words, turn into `From' followed by some
words.

For example, if I send a Python script containing:

from __future__ import division

it will turn into:

>From __future__ import division

This problem occurs only when there is a secure-pgpmime-sign marker.


In order to retproduce:


emacs -Q

C-x m

C-c RET C-s

Example email (you must have working GPG with keys for bob@example.com):

-----EMAIL START-----
To: alice@example.com
Subject: from test
From: bob@example.com
--text follows this line--
<#secure method=pgpmime mode=sign>
hi

from __future__ import division

from
from asdf
from

subject
subject asdf

bye
-----EMAIL STOP-----


After sending such email or pressing `Preview' in the toolbar the
message turns into:

-----EMAIL START-----
From: marekrud@gmail.com
Subject: from test
To: alice@example.com

hi

>From __future__ import division

from
>From asdf
from

subject
subject asdf

bye
-----EMAIL STOP-----

If you need any more information, please let me know per email.

Thank you
Marek
