Build Date & Platform Bug Found:
 Win32 commercial seamonkey build 1999-12-02-11-m12 installed on P166 Win98
 Linux commercial seamonkey build 1999-12-02-12-m12 installed on P200 Redhat 6.1
 MacOS commercial seamonkey build 1999-12-02-12-m12 installed on G3 MacOS 8.6

Overview Description:
If you reply to a plain text message that was sent from 5.0 using a plain text
editor, the message is sent with the wrong Content-Transfer-Encoding. It states
it 8 bit instead of 7 bit.

This problem occurs only if I reply to a plain text message that was sent from
5.0.  Plain text message sent from 4.7 win32, does not appear to exhibit this
problem.

Steps to Reproduce:
0) Edit your prefs.js file and change the user pref to false for
   user_pref("mail.identity.id1.compose_html", false);
1) Launch Seamonkey
2) Start Messenger
3) Start a new plain text message
4) Send the message to yourself, add a title, and couple of sentence of text
   Be sure not to use any extended characters.
5) Send and receive the mail message
6) Reply to the plain text message
7) Use Communicator 4.7 to view the message page source.
   The Content-Transfer-Encoding is 8 bit instead of 7 bit.

Actual Results:
The page source says the message is Content-Transfer-Encoding: 8bit

Expected Results:
If there are no extended characters in the mail message, it should be 7 bit.

Additional Builds and Platforms Tested On:

Additional Information:
Note: I did double check that my original mail message was 7 bits and had
 Content-Type: text/plain; charset=us-ascii; format=flowed
 Content-Transfer-Encoding: 7bit

Doesn't seem like there are any user-visible problems with this, so pushing past
B1. Feel free to move it back if I'm mistaken.

Good catch Peter! It makes my life so much easier (not to mention a better 
product) when you guys dig these issues.

I have a fix in my tree and will check in if the tree opens today.
