226364 - Plain text message lines combined to fill window's width

Status: RESOLVED DUPLICATE of bug 197130

(SeaMonkey :: MailNews: Message Display, defect)

Description

[Simcha-Yitzchak Lerner]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.5) Gecko/20031007
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.5) Gecko/20031007

If I receive a message in plain text, even though the lines are shorted than the
width of my window, adjactent lines are combined together to fill the width of
the window.

This should never happen, but even worse, it continues to happen even if I have
turned off the "Wrap text to fit window width" option.

Reproducible: Always

Steps to Reproduce:
1. In Mail & Newsgroups Account Settings, under composition and addressing, turn
off "Compose Messages in HTML format".  Also, under Preferences, Mail &
Newsgroups, Composition, set "Wrap plain text messages at 72 characters" (this
is the default).
2. Start a new mail message, addressed to yourself.  Type in a few paragraphs,
allowing the text to wrap for several lines each.
3. Send the message and then view it in a window as wide as your screen (wider
than 72 characters).
4. The message now displays wrapped to the width of the window, regardless of
whether the "Wrap text to fit window width" option is on or off.
5. View source of the message shows that the lines were indeed sent with the
text wrapped at 72 characters.

Actual Results:  
The text message is wrapped to the window's width.

Expected Results:  
The lines should have displayed as sent, wrapped at 72 characters.

If some consider this a desirable behaviour (I don't), perhaps you need two
options.  One to "Wrap LONG text to fit window width", and one to "REFORMAT text
to to fit window width".

The reflow you are seeing is the result of the format=flowed spec.  The message 
was composed and transmitted as f=f, and Mozilla handles f=f by default to 
reflow the message text.  You can turn it off: set the preference
  mailnews.display.disable_format_flowed_support
to True.
See bug 168420 for an overview of format=flowed, including a FAQ.

The program is working as designed, therefore this bug is marked Invalid.
I suggest voting for one of the related bugs, particularly bug 86607.
