711187 - Composition of format=flowed messages wraps lines using hard breaks

Status: UNCONFIRMED

(Thunderbird :: Message Compose Window, defect)

Description

[Ilguiz Latypov]

User Agent: Mozilla/5.0 (X11; Linux i686; rv:8.0) Gecko/20100101 Firefox/8.0 Iceweasel/8.0
Build ID: 20111130203654

Steps to reproduce:

I have IceDove in debian sid,

Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.2.24) Gecko/20111114 Lightning/1.0b3pre Icedove/3.1.16

I started a new message with the flowed format composition and display enabled by default. 

I pasted long lines using Ctrl+Shift+V to make them look as quotation.

They appeared unwrapped, as I expected.  After reading the format=flowed RFC 3676, I figured that the composer will soft-wrap the long lines using SPACE CRLF and re-quote the wrapped lines.

> LONG LINE

I sent the message and opened the source view of its IMAP-saved copy in the Sent folder.



Actual results:

I saw the long lines wrapped at a big boundary of magnitude 100s to 1000s characters.  Each wrapping consisted of a sole line break without the preceding space character that I expected.

The start of the continuation line did not have a quotation mark.

> LONG LINE PART1[LF]
LONG LINE PART2



Expected results:

I expected that the composer made the sent copy look better both for non-format-flowed-aware and for format-flowed-aware MUAs.

[SP] > LONG LINE PART1 [SP] [CR] [LF]
[SP] > PART2

(I am not sure about the space-stuffing each quotation mark, but the RFC appears to mandate this).

just looking at the summaries without reading the bugs, could this be related to bug 26734?
