477541 - Flowed plain text does not trim spaces prior to hard line breaks

Status: VERIFIED DUPLICATE of bug 261467

(Thunderbird :: Message Compose Window, defect)

Description

[Jeremy White]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.4) Gecko/2008112309 Iceweasel/3.0.4 (Debian-3.0.4-1)
Build Identifier: 2.0.0.19

According to RFC 3676, a generating agent SHOULD trim spaces before user-inserted hard line breaks.

A brief inspection of nsPlainTextSerializer.cpp shows no sign of Thunderbird doing this, and testing suggests that it does not.

The end user effect is that if you type this:
  carefully formatted oops
and then left control arrow to the 'oops', hit enter, and type so the line reads
  oops message
(i.e. make sure to leave a trailing space)

instead of seeing what you saw:
  carefully formatted 
  oops message

the recipient instead sees a single line:
  carefully formatted oops message

Reproducible: Always

Steps to Reproduce:
1. Create a new message in a default Thunderbird (e.g. flowed send is on)
2. Type 'carefully formatted ' (note trailing space), Enter,
   and then 'oops message'.
3. Note current visual appearance; e.g. 2 lines.  
4. Send email
Actual Results:  
1. Visible email received appears all on one line.

Expected Results:  
Visible emails should have 2 lines.

Ah, forgot to mention - you have to have wrap set to 0.  Apparently wrapping turned on will mitigate this.

This appears to be a dupe of bug 261467, which is fixed in trunk.

Comment 4

VERIFIED to be fixed on trunk with both plaintext composer and HTML composer.
