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
Date: Thu, 29 Jan 2015 11:05:00 +0100 (13 seconds ago)

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

Was someone to able to reproduce bug #19726?  Or is it caused by some
mis-configuration on my side?

Thank your for help with that!

OK, I tried this.

Well, the problem is similar - I'm not saying that it's related (and in
fact it appears it's not).

I just tried, and it seems not.  Does it persist on your side?  (If not,
I'd be inclined to close this bug.)

I think I could try one more thing (but not today - it's Easter Eve, and
my family will soon be awake!): checkout the Emacs version from the time
you reported this bug, compile it and see whether I could observe it.

Thanks, I understand now.

I currently use GNU Emacs 24.5.1 which still hast this problem.

I quickly tried version 25.0.92 which seem to have it fixed.

For me you could consider closing this issue, because the new Emacs
version should be released sooner than later and the workaround (at
least for Python files) is to send them as non-inline attachments.
