User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.0.19) Gecko/2010031422 (CK-Amazon.com) Firefox/3.0.19 ( .NET CLR 3.5.30729)

When saving E-Mail messages from the folder message listing with Control-S (creates .eml files with the subject as the filename), lines in the body text that start with a period/full stop/decimal point, have that period/full stop/decimal point truncated. Lines like this:
.one dot
..two dots
...three dots

become:
one dot
.two dots
..three dots


Reproducible: Always

Steps to Reproduce:
1. Compose a new message with three lines in it:
.one dot
..two dots
...three dots

2. Save that message as a Draft, and review it to make sure it still has the correct number of dots at the start of each line

3. Save that draft message to disc (Control-S) from the drafts folder message list, and then open the .eml file in a standard text editor.  Each line will now be missing one dot.

Expected Results:  
The saved file should contain the same exact message body that you see in the Draft message.

If you open the draft message, and use "Save-As File" instead, the file will be saved as a .txt file, and the dots will be intact.

I have the following config option changed from the default:

mailnews.send_plaintext_flowed;false

Although changing that setting didn't appear to make any difference.

I am using the default theme, and have only one add-on installed, Toggle Word Wrap v1.4

I also noted that this bug was present in TB v2.x which I just upgraded from.
