317740 - Forward inline shows hard line breaks

Status: RESOLVED DUPLICATE of bug 249093

(Thunderbird :: Message Compose Window, defect)

Description

[Nicolas Marchildon]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.10) Gecko/20050911 Firefox/1.0.6 (Debian package 1.0.6-5)
Build Identifier: Thunderbird version 1.0.2 (20050602) Debian package

In my prefs.js, I enabled format=flowed, so that messages I send have "Content-Type: text/plain; format=flowed":

user_pref("mailnews.send_plaintext_flowed", true);
user_pref("mailnews.display.disable_format_flowed_support", false);

This works fine unless I forward such a message I received. The compose window shows the From/Date/To headers in a table, followed by the original text. This text has wrapped lines, making user assume format=flowed is lost.

However, when sending the mail as plain text, the format=flowed is added to the outgoing message.

An even more incoherent behavior is observed when I add a line break to the forwarded message content. Let's say I have "asdf asdf asdf" repeated many times on one line and I forward it, it would show as -let's say- 5 wrapped lines. If I add an empty line by hitting Enter, and enter some text (such as "yo!"), then send that to myself, the result looks weird:

The message appears as one single line (remember the format=flowed setting), except this: the text I added on a separate line, after the manual break, actually shows on the same long line, followed by a line break, and the rest of the long line.

Reproducible: Always

Steps to Reproduce:
1. Close Thunderbird
2. Append this to your prefs.js:

user_pref("mailnews.send_plaintext_flowed", true);
user_pref("mailnews.display.disable_format_flowed_support", false);

3. Open Thunderbird
4. Compose message with "asdf"+space ("asdf ") repeated many times, so that text wraps on 4-5 lines (let's say total of 500 characters)
5. Send message to yourself as plain text (Options | Format | Plain Text Only)
6. Get Mail
7. Click Message | Forward As | Inline
8. Observe hard line breaks (text does not adjust to window size)

Additional observation:

9. Insert line break by hitting Enter in middle of forwarded message, at beginning or end of line
10. Type "hello"
11. Send message to yourself
12. Get Mail
13. Observe format=flowed is in source (CTRL-U)
14. Observe "hello" appears on same line as "asdf asdf...", followed by a line break, and the rest of "asdf asdf...".
Actual Results:  
8. Observe hard line breaks (text does not adjust to window size)

14. Observe "hello" appears on same line as "asdf asdf...", followed by a line break, and the rest of "asdf asdf...".

Expected Results:  
8. Text should appear like original in inbox (long lines flowing, wrapped at window width)

14. "hello" should appear on its own line, just like it was in the Compose window.

This is mainly an annoyance. Since the long line is preserved once the forwarded message is sent, it is not a big problem for me.
